| Notes: | Chronometer. The same as cal. 5625 but with day display (as well as date). The plastic star-shaped date corrector wheel is fragile and prone to breaking, resulting in the day/date setting not working. As these watches get older, it’s getting harder to find unbroken replacement wheels and creating new ones, e.g. from brass or other metal, is fiddly and time consuming. |
