Bought for the second time me this clock. The first held 3years, I have broken the glass while working and at the price is not worth repairing. The clock is pretty much the most stable clock, which I've had to work on construction sites. Introduces you to all, regardless of whether dust, oil, dirt, grease or water. Briefly rinsed and is ready for use again. Even the bracelet that looks at first glance like cheap plastic is super stable. So who is looking for a robust job clock, which is served here well.
