I have this clock for 11 years. Already that they will be built still unchanged today, speaks for them. I had the clock in this period the Citizen Service, because the work was gummy once. It runs super accurate and is very robust. I dive too! Can only positive to say about the clock. Of course you have set the date for an automatic, unlike the quartz clock every 2 months. Has never bothered me. Battery replacement (expensive at diving watches) omitted it. P.Bader
