I ordered the stopwatch, because I to stop several time intervals (has nothing to do with sport) need for my profession. It comes down to the exact second to capture a plurality of intervals, when the clock disturbs it. First of all it absolutely practically that the clock 60 intervals (or in sports rounds) records and you just "click" must be. The times can then be written off in peace. Very good is also our own adaptation of 12- to 24-hour mode. The beep as confirmation of the button press is extremely loud. Should probably be so. I was very disturbed it (because I would indeed use the clock otherwise) and wanted to consciously take the beeping out of service, although this will invalidate the warranty. So unscrewed rear cover, there also the battery is finally changed. When the lid was off, I could see a round contact and a membrane in the lid. Also put two small springs in the clock, the press precisely when closing the lid on the contacts. So I removed the feathers, because I assumed that the membrane of the speaker. And, after assembly, the clock is actually silent as a fish. Totally cool, extinguished no guarantee and the beeper would later go (ferdern very very good pick!).
All in all I am very very happy with the purchase and may each recommend this clock. Very solid build quality, good readability and functionality. The only negative thing I realized is the display, which can not be switched off. This means that the clock is always constant. She arrived already in this state with me. That is why a star deduction. Let's see how long does the battery thereby. Delivery by Amazon must not be commented. It went so fast, so I must assume that Amazon guess what I'm going to buy next and it submits before ordering. If there Bäckerbrötchen Amazon: you were at the delivery still warm ...
