Product reviews

On September 17, 2025, I ordered the Certina DS Action Diver 40.5 mm with the Powermatic 80 caliber, the titanium version with a steel bracelet, from Christian Uhren. On September 18, 2025, I received the watch from the post office after signing for it. This was my first joy; I hadn't expected it to arrive so quickly. When I tried the watch on, I noticed that the 40.5 mm size was ideal for my 18.5 cm wrist. I had the strap adjusted by a watchmaker. When I finally wore the watch, I immediately noticed how pleasantly light it was. Now for my experience after wearing it for a good month: Daytime legibility is very good, everything is beautifully crafted (indices, hands, bezel). The Powermatic movement lost 3 seconds on me after 21 days, but that's perfectly fine, since I always wear the watch (except at the gym), but I put it back on when I shower and wear it constantly. I won't go into detail about the inner workings, i.e., the technology, as that is sufficiently described in the watch description. At night, the indices aren't very bright, and the hands aren't particularly bright for an advertised diver's watch. The luminosity doesn't fade as quickly as I've experienced with other watches, but in general, the luminosity could be better. Now for the bracelet: the titanium alloy doesn't prove to be very scratch-resistant, nor does the clasp; after a month, it already looks as if I've worn it every day on the construction site, even though I have an office job. Here, too, I have to say that if this is to be a true diver's watch, it needs to be more durable. The micro-adjustment is excellent; there's nothing to complain about. I also think the quick-release mechanism for quickly changing the strap is great; the strap quality could just be a bit better. Conclusion: A great watch, wearable for any occasion. If the luminosity and the strap (clasp) were even better, there wouldn't be a better Swiss diver's watch on the market for this price.
