Today's offering showcases this original c. 1940's Swiss two-register chronograph in 18K rose gold with tachometer scale.

It has a pleasing dial and stylish rose gold design.

Chronograph watches were originally designed as precision instruments, serving the needs of doctor's, pilots, auto racers, sportsmen, and other professionals who demanded a high level of precision in their timing. Equipped with special functions to aid the wearer in the task at hand, these fine mechanisms played an integral role in their owner's lives.

Two of the most utilized features on a chronograph were a special dial for timing events up to 30 minutes in duration and a tachymetre scale for easily determining speed and distance, such as on this watch.

This watch is powered by a Landeron caliber 48 movement. For those unfamiliar with chronographs, due to their complexity, in vintage times most brands, including respected firms like Rolex, Breitling, and Heuer, did not manufacture their own chronograph movements but rather purchased them from companies who specialized in making the sophisticated mechanisms.

One of the main chronograph movement makers of the period was the the Swiss firm Landeron. Their movements are well-known for powering some of Heuer's and Baume et Mercier's chronographs, as well as watches from Gallet and a number of other Swiss watch houses.

Our watch has original parts down to the pushers and hands - the only part that has been replaced at some point is the winding crown. Our watchmaker has freshly cleaned and oiled the movement. The chronograph resets crisply and to a perfect zero.

For the finishing touch we have equipped it with a brand new Teju lizard strap making it ready for immediate enjoyment.

Included with the purchase is a one-year C.O.T. warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.
