CertinaMens, DS Action Diver 38mm Powermatic 80, Titanium, Swiss Automatic, Watch, Anthracite, Plastic, 19, (C0328074808100)

First, the watch arrived in the appropriate box, along with the warranty card, manual, and certificate of the ISO standard for diver's watches. Be aware that as a diver's watch, it does feature a screw-down crown, so you will need to unscrew the crown to wind the watch and adjust the time.Second, yes this is a Powermatic 80 movement. Yes, it is the same overall design commonly used in Tissot watches. They are both owned by the Swatch Group and share parts. My experience it is gains a few seconds a day, but is well within specification per the manual.I've worn it for a few weeks. It is comfortable and lightweight due to the titanium case and nylon band.Finally, Certina does not have any retail locations in the US. They can only be bought at a handful of online stores. However, since they are a Swatch owned brand, they can be serviced at any of the three Swatch Group service centers in the US.
