Omega Chronograph Cal.33.3/170 1942 Breguet Dial

Omega Watches

Since the company was founded in 1848, Omega has pioneered a huge range of innovations. Britain’s Royal Flying Corps chose Omega watches in 1917 as official timekeepers for its pilots and again in 1940, RAF Pilots watches were supplied by Omega. The 1940s also saw the first tourbillon wristwatch and the first of the famous Seamaster watches, whilst the 1950s and ’60s introduced the legendary Constellation, Speedmaster, Seamaster 300 and Railmaster. Over these years, everyone from John F. Kennedy to Elvis wore Omega watches on official duties. What’s more, in 1962, astronaut Wally Schirra took his Omega Speedmaster into space on NASA’s Mercury Sigma 7 mission and in 1969 two Speedmasters landed on the moon, worn by Neil Armstrong and Buzz Aldrin.

Omega was a pioneer of the wristwatch chronograph, releasing its first model, the 18′ CHRO, in 1913 making this one of the very first wrist-worn chronographs ever produced. These were sold as military watches with some of the first going to Britain’s Royal Flying Corps and used by some of the most famous wartime pilots and military personnel. Omega recently re-issued a heritage edition of this chronograph which has generated considerable interest in all of its original early chronograph models.

In 1930, Omega and Tissot merged, with the aim of marketing high-quality Swiss watches. Omega would maintain its position in the medium-high luxury segment and Tissot would target the medium market. Subsequently, in 1932 the company bought Lemania, a Swiss company specialising in the manufacture of high-quality chronograph movements, founded in 1884.

The Calibre 33.3 movement followed, designated 13CH by its manufacturer Lemania. It is a column-wheel movement, which was very advanced for the period and highly accurate and reliable. Later evolutions of this movement included the 33.3 CHRO T1, T2 – T6, becoming the Omega 170 in 1949, and the Omega 171. Such was the complexity and expense of this movement that only 13,700 were produced between 1933 to 1952.

A development of the Cal. 33.3, the Cal.15TL two-pusher chronograph movement is notable as the most long-lived Lemania movement and its first movement with a flyback function. This was adopted by military forces around the world from Czechoslovakia, Rhodesia, the British Royal Air Force, the French Air Force (Auricoste Type 20), the Swedish Air Force, the South African Air Force, the South African Air Force, the Royal Canadian Air Force etc.

In 1942 the Calibre 15TL movement was further improved to offer anti-shock and anti-magnetic properties. A new version for water-resistant chronographs spun off in 1949 before the end of production of the movement in 1952. In parallel, in 1949 and after a number of modifications to these predecessor movements, the Lemania Cal.27 was born. This calibre is known under a far more famous name: The Omega Cal.321. This was, of course, the movement used in the 1960s Speedmaster, chosen by early Gemini and Apollo astronauts and later adopted by NASA for use on all the Apollo moon missions.

Description

A wonderful previously restored stainless steel Omega Chronograph wristwatch, with a wonderful twin-register, silver dial with Breguet style 1 – 12 standard Arabic numerals. The outstanding stainless steel case measures 37mm, excluding the correct unsigned crown, making this an oversized watch today, this watch also carries a high-grade Omega calibre 170 hand-wound movement which is in sparkling condition.

The Dial

The beautiful previously restored silver dial is in wonderful condition as are the beautiful blued steel ‘lance’ hands, making the dial very easy to read. These are also original and are an outstanding feature of this watch. The dial also carries attractive bold black, Breguet style 1 – 12 standard Arabic numerals.

This dial carries a twin register, the dial at the left by 9, indicates the elapsed time of up to thirty minutes while the chronograph is running, and the dial at the right by 3, indicates the elapsed time of up to 30 minutes.

The dial is simply signed ‘Omega’ at the very top of the dial just below 12 along with ‘Swiss’ at the very bottom of the dial below 6.

This dial has been previously restored to a very high standard, yet remains in outstanding condition, as can be seen in the photographs.

The Movement

The movement within this watch is the Omega calibre 170, 17 Jewel hand-wound chronograph movement which is in sparkling condition and has been fully overhauled and serviced by our vintage specialist watchmaker. This means the movement has been completely disassembled, cleaned, inspected and rebuilt using only the correct original parts where required before careful calibration and testing. Upon returning to stock, the watch is now running to within +8 seconds per day which is truly outstanding for any vintage watch of this age!

With care and with regular servicing, say every 4 years, we would fully expect this watch to run quite happily for many decades to come. We are therefore more than happy to offer this watch with our 12 months’ warranty* and to assist with servicing again in the future.

The movement is correctly signed ‘Omega’, along with the calibre 170 and 17 jewels.

*Please note – our 12 months’ warranty is only applicable if the list price is paid.

The Case

The three-piece stainless steel case measures 37mm in diameter, excluding the unsigned Omega winding crown, making this watch an oversized watch for this period. The case, as we would expect from Omega, is very solid and well made and the press-fit case-back closes with a very solid and satisfying ‘pop’, indicating the case has been impeccably built and maintained. It is of full-thickness and has never been engraved.

Having been cleaned, carefully examined and lightly hand-polished by our case-maker, the case is totally immaculate, being very crisp with no scratches, dings or other blemishes visible to the naked eye. This, along with the superb general condition of the rest of the watch, indicates this watch has received an excellent level of care and only light use.

Inside the case-back all is correct and as expected. It is signed with ‘Omega Watch Co’, ‘Fab Suisse’ and ‘Swiss Made’ along with the case serial number 9712480.

As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.
