For more than 34 years the name Auktionen Dr. H.

Crott has stood for competence in timepieces.

Founded 1973 in Aachen by the expert and collector

Dr. Helmut Crott, the auction house rapidly

established an international reputation as a

reliable partner for watch and clock enthusiasts.

After many years of dedication to the business,

Dr. Crott retired in 1993 and passed his successful

and distinguished auction house on to Stefan

Muser. To this day the company carries the

name Dr. Crott, with whom we share a deep and

trusting relationship and who still holds an intense

interest in the development of the auction house.

Auktionen Dr. H. Crott moved to Mannheim (near

Frankfurt/Main) in 1994, where the excellent

infrastructure makes for easy access for the ever

increasing international customer base. In Mannheim

the success story of Auktionen Dr. H. Crott

now continues into its 35 th year.

Proprietor and Auctioneer

Born in 1963 in Mannheim, Stefan Muser, the son of

enthusiastic collector Hans Muser and his wife Gisela,

was infected at an early age with the timepiece bug.

For more than 30 years now Stefan Muser has been

dedicating himself to timepieces and their history;

what started out as a hobby quickly became a vocation

and a career. Today Stefan Muser is one of the world’s

most renowned experts in his field.

Proof of his professional competence are not only his

numerous publications on the subject of auctions and

performance of vintage watches, but also the detailed

and lovingly designed auction catalogues of Auktionen

Dr. H. Crott.

Stefan Muser is married and has two children. His wife

Annette and other members of the family are involved

in the company, so that this can justifiably be called

a true family business. It allows a stable and close

personal contact with the clients and collectors, and

ensures a long-term commitment on both sides.

Because of his passion, his solid experience and his

profound knowledge in his field of activity, Stefan

Muser has played a major role in determining the

pricing in the international watch and clock market

for many years. His excellent reputation amongst the

collectors has proven to be an ideal platform for

the successful sale or purchase of collections and

objects of the highest quality, which he sees as the

only way to achieve maximum results!

Selling at Auctions – why?

Umschlag75 04.09.2007 10:15 Uhr Seite 1

To sell collectable pieces at an auction has many

advantages. Objects achieve their real value during

75. Auktion

an auction, a fact Pierre-Auguste Renoir Hotel Sheraton, (1841–1919)

Frankfurt Airport

Freitag, 23. November 2007

already realized in the nineteenth century: “You must

be aware of the fact that there is only one place

where the value of the paintings is recognized, and

that place is the auction hall”.

Just as true for timepieces as it is for paintings,

during an auction the market mechanism ensures

a transparent determination of a fair market price

Umschlag_aussen77 16.04.2008 10:27 Uhr Seite 1

much easier than anywhere else – here is where

supply and demand truly meet.

And a competent and experienced auctioneer

plays a decisive role in the achievement of the

highest prices by encouraging and controlling

the dynamics of the bidding.

Auktionen Dr. H. Crott attracted a great deal of

attention in this respect during its 69th auction in

November 2004, where a rare Patek Philippe steel

chronograph (ref. 1518) was presented. Reaching

a bidding price of almost 1.3 mill. Euros, this is

Umschlag_aussen78:Layout 1 19.12.08 12:35 Seite 1

a German record for a wristwatch at auction that

auctioneer Stefan Muser still holds to this day!

The determination of the limits is done during the

run-up to the auction by our competent and

experienced team under the guidance of Stefan Muser;

the exact expertise of the objects in combination with

the analysis of the market situation ensures on the

one hand that none of the watches and clocks are

sold under value, and on the other also offers accurate

guidelines to the collectors wanting to purchase.

The Auctions

Several auctions are being held per year; each

and every one is carefully and extensively

prepared. The diverse special auctions offer a

comprehensive range of watches and clocks of

all epochs and are also a popular and attractive

meeting point for many renowned collectors,

dealers and experts. Bidders who cannot attend

or wish to remain anonymous can either deliver

a written bid or bid per telephone during the

auction. With regard to our international

customer base we have chosen the Sheraton

Hotel at Frankfurt Airport for our auctions, an

elegant venue with perfect infrastructure. This

makes for easy transportation for our national

and international clientele, and the hotel can

be reached directly from the airport terminal

via a pedestrian overpass.

Should you require an expert evaluation of your

timepieces in the comfort of your own home,

it will be a pleasure for us to accommodate you.

Especially where very high-quality collections

are concerned we lay great value on personal

on-site consultations, worldwide. For a free-ofcharge

and non-binding estimate, please send

us the photographs of your objects to


After consignment our dedicated team sets

about preparing for the auction. All objects are

professionally photographed and extensively

documented. This complex and time-consuming

process is the prerequisite for presenting the

timepieces in an appropriate setting in our

high-quality multilingual auction catalogues

and of course on our company website


In the course of our company‘s history we have

established a large international customer base

including many museums, dealers and private

collectors; all our clients receive their copy of our

catalogue in the run-up to the auction.

Carefully placed national and international

advertising campaigns as well as intensive press

and PR work help publicise the range of objects

presented at the auctions.

Excerpts from our auction catalogues:


Uhrenfabrik Union Glashütte in Sachsen Movm. No. 44502,

circa 1902

An important Glashuette gold hunting case pocket watch -

of museum quality so called “Grande Complication”

Case: 18K gold, 394 gr., 75mm diameter, Lucia à goutte form,

tiered, 5-part hinges, central part with two pushers for split

seconds chronograph and slide for minute repetition, lever for

inner five minute divisions, sunk day-, date- and month indication

counter, cobalt blue enamelled golden moon phase disc with

applied gold moon and stars, auxiliary seconds, flying fifths of a

seconds indication “seconde foudroyante”.

Movm.: 2/3 plate movement, frosted, gilt, gold-chatoned, blued/

As Bernd Schaarschmidt reports on the history of the

Glashuette watch company “Union”:

“… A masterpiece of our local watchmaking industry was recently

presented and explained to us in great detail by a representative

of the company ‘Union’ Duerrstein & Co., Glashuette and Dresden,

makers of precision watches. This complicated work of art, which

represents a quite considerable amount of value, has an 18K gold

case and weighs about 300 grams. The watch was made to order

and is the 6th of its kind (!); it shows date, day of the week and

month and automatically adjusts the date and the leap year. The

reading of the time is exact to 1/5 of a second. The watch repeats

the minutes and strikes the quarter hour and the hour.” (From

a record dated May 1898)

Another recount from a visit to the „Union“ watch company in

September 1902 states:

“Mr. Bergter, the director of the Duerrstein watch company

‘Union’ showed us two special new precision pocket watches in

gold cases and told us, that he did most of the design work as

well as the actual manufacturing himself.”

The watches referred to were nos. 55806 and 44502. The exquisite

execution of the steel parts as well their harmony and beauty are

a fine example of the unmatched craftsmanship of Julius Bergter

and Martin Simmchen.

A gent‘s almost as new Geneva wristwatch – additional

silvered dial and additional hands-set with original box,

certificate, owners manual and papers

Case: steel, three-body, screw back, movement protection cap,

Movm.: rotorwind movement, rhodium-plated, ground, 8 adj.,

26 jewels, mirror-polished screws, Glucydur screw balance, shock

protection for balance, cam type fine adjusting device.

Ref. 1019

The reference 1019 was first produced in 1966 and always has

a polished bezel. The name “Milgauss” is a combination of “Mil”

(a thousand), and “Gauss”, (the unit of the measurement of

magnetism). Normal movements can take up to 70-80 Gauss;

anything higher comprimises their working order. Good watches

usually resist magnetic fields of 60 to 70 Gauss; the “Milgauss”,

however, keeps its astounding precision in magnetic fields up

to 1000 Gauss. The watch‘s dial, ring and cover of its movement

are made in soft iron forming a Faraday cage – Rolex managed

to create a brilliant solution to the problem. Carl Friedrich Gauss

(1777–1855) was a German astronomer, mathematician and

physicist; he published several important works on celestial

mechanics, geodesy, magnetism, electromagnetism and optics.

The English chemist and physicist Michael Faraday (1791–1867)

was known for his groundbreaking experiments in electricity

and magnetism. Many of his concepts were derived directly from

his experiments (such as lines of magnetic force) and became

common ideas in modern physics. Gauss – a magnetic induction

unit, symbol “g” in the C.G.S. system. The watch is illustrated

in “Rolex, Collecting Wristwatches”, by Osvaldo Patrizzi, 2001

Edition, pp. 352, 353.

This clock has always been called the “Quitzin clock” because

Schloss Quitzin was its first home. The clock has a truly

fascinating history; The Counts of Kuessow were a very wealthy

family whose peerage began in the early 17th century. The first

owner of the clock is assumed to have been Erasmus Ernst

Friedrich Kuessow, who married the Swedish Countess Reinschild

and was chamberlain (Gentleman of the Bedchamber) to the

Elector of the German Empire and Real Privy Councillor of Vienna.

Apparently a great traveller, it is most likely that the Earl bought

the clock on one of his travels. Of the thirty estates belonging

to the Earls of Kuessow, the ancestral seat was at Quitzin in the

district of Grimmen in Mecklenburg-Vorpommern. In 1757 the

Earl died of the plague in Vienna and over several generations the

clock passed to a succession of female heirs. When the Red Army

invaded the country, confidant of the family was quick-witted

enough to hide the clock in a cupboard and to store this in an

attic in the castle, where it remained for many months. When the

chaos of the invasion had subsides, the cupboard with the clock

was taken 24 kilometers to the town of Stralsund under the cover

of darkness. The clock was then loaned to the local museum in

the hope that it would be protected there. Meanwhile the family

had fled to West Germany, knowing that it was highly unlikely

that they would ever see their clock or the family estates again.

When the political situation had changed in Germany, the family

returned to the East in 1990 and found that the clock had

survived safely in the museum.

Your Watches and Clocks are in Safe Hands with

Auktionen Dr. H. Crott!

The fact that we are a family business with a

strong bond between all our team members and

ourselves ensures full commitment to the task at

hand. The intensive personal contact we keep with

our clients is very different from the anonymous

assistance one so often gets from an enlisted

staffer. Of course Stefan Muser himself is always

happy to be directly of service and answer any


Maintaining our close relationship with all the

enthusiasts and institutional collectors worldwide

is a prerequisite for long-term customer retention,

which on the one hand repeatedly brings collectors

from the furthest corners of the world to our

auctions and on the other also enables us to offer

so many interesting, precious and rare objects at

these events.

Limiting Auktionen Dr. H. Crott to the auctioning

of collectible timepieces has allowed us to focus

and dedicate all company resources on this

market and its special requirements. The team

perfectly combines its enthusiasm with a strong

competence in the sector, which permits us to

offer all the required services for achieving a

perfect auction – from the primary valuation of

your objects by one of our capable experts to a

successful sale. Many years of experience in the

field allow us to make a first-rate determination of

the current market value of your timepiece.

To conduct an auction successfully one must pay

extensive attention to detail, taking the many

varied influences on the market into consideration

– expert knowledge is essential here!

The watch and clock market is subject to strong

seasonal fluctuations for example; due to our

expertise this can be used to the advantage of

our clients.

In the field of evaluating and trading Riefler

precision pendulum clocks and Glashuette

watches we are the unchallenged premier

auction house worldwide – this makes each and

every one of our auctions an event not to be

missed by any specialist collector, and enables

auctioneer Stefan Muser to achieve record bids

on a regular basis!

Our professional reputation is such that even

world famous collections like that of expert

and collector Gerd Ahrens are entrusted to us;

in 2007 this was a collection of such size and

importance that it demanded its own catalogue.

The special “Ahrens Auction” was a milestone in

the history of our house and set new standards

for watch auctions at the highest level! With

a sales quota of 97% the auction rendered

proceeds of approximately 2.4 mill. Euros for

about 600 watches and was an internationally

celebrated occasion.

The group of those who consign to our auctions

spans a large range: from the grandson who was

given his grandfather‘s aviator‘s watch to the

owner of an exceptional collection such as the

Ahrens collection – and we pride ourselves on

being a fair and competent partner for each and

every one of these timepiece enthusiasts!

Auktionen Dr. H. Crott’s exclusive specialization

on watches and clocks is the major advantage for

our clients.
