It also says that the balance wheel has an anti-shock device, which is useful information. alpina watches Founded in 1883, Alpina, famous for its signature red triangle, is a fine watchmaking manufacture based in Geneva, Switzerland with a history spanning more than 135 years. The style of the movement could date anywhere between about 18, but that number 335 on the movement under the name Alpina is a good clue - that is the "calibre" number, which describes the layout of the movement, and fortunately there is an excellent website which has gathered a huge database on Swiss calibres - Ranfft Watches - and if you click on that link you will see your movement, serial number 659658 (very close to your serial number) and on the right there is information which dates it to about 1930. The watch functions are extremely easy to operate, all through the timepiece’s single. The watch dial displays the time in 24 major world cities, as well as a night/day indication and a small date at the 6 o’clock position. Unfortunately, very few European manufacturers retained their ledgers, so they are of no help in dating. Our engineers developed the AL-718 World Timer complication, at the heart of which is our AL-710 Manufacture calibre. That number on the movement, known as the "serial number", would indeed date the watch if anyone had the ledgers of the company which recorded the information. ![]()
