3 hours faster than normal every day

The which was almost 3 hours faster than normal every day and could not be used at all. I really felt very troublesome. What can I do?

A beatiful timepiece!

This is really a beautiful timepiece. It also is very durable and quality build. I love the design and you can see through one part of the watch, all the way through the back. Very easy to set and use. 3 buttons on the sides of the watch set the day, month, and date. While the crown sets the time itself. The size is the same as any normal watch, not to large. The mechanics and watching those run is also very satisfying. I have received many complements. Would recommend for the spend level, this watch is a great buy!

Mooi horloge voor interessante prijs. Vrij zeldzaam is de open hart in combinatie met datum aanduiding. Minpunt is de kleur van de dag en maand wijzers. Die zijn te donker ten opzichte van de wijzerplaat en daardoor moeilijk af te lezen. Er zijn andere modellen met een beter contrast
