Lemania 1873 HW Chronograph

Water Resistance
Very high water resistance: 10 atu, but not for this my watch having been under halogen lights in the shop for such a long time. I would not want to test that 100 m water resistance. Although the watch features a triplock crown. But the pusher o-rings will certainly not meet the water resistance rating anymore. But then who wears a Dress Chronograph for diving anyway?
