It was originally purchased, because I need an absolutely waterproof clock, which must be reasonably shockproof. An automatic system is too expensive for me to drive in acceptable quality in order to work or sport, and I want no clock that must be opened to change the battery.
This clock is self-sufficient because of their solar panels in the dial on for years, therefore, always waterproof and very well made for the price. The quartz movement loses with me about 30 seconds a month; because you already have to correct the calendar every two months, it is thus entirely satisfactory precision. The bezel is required in my view, little attention, especially if you often carries the clock in the water: after drying a couple of turns and it is ensured that the mechanism does not become clogged with dirt. Otherwise, I would do it once a week under running water, in a dusty environment somewhat more frequently.
Overall, the clock is very presentable, the metal is worked beautifully matte and feels very comfortable. It is easy to clean and the rubber bracelet is still comfortable to wear even in heavy sweating on hairy wrists (whom the printed "Hello, I am a diver" table interfere: there is the bracelet separately without).
Who is looking for a clock that shows no weakness outside playing sports or working, at night is easy to read and easy is always reliable, can not go wrong here. In particular, the battery requirement is almost enough reason to buy d.
