I point all this out not to complain, but rather to give some context to what I’m about to say: this watch wears much larger than you’d expect, and those measurements paint a clear picture as to why. On the wrist, I noticed this watch a lot more than I thought I would, especially during activity or bending my wrist at all. Its measurements don’t seem that far off the (similar) Autodromo Group B, but in practice, that watch melts off the wrist, where the Tissot makes its presence felt. It’s not uncomfortable, but I wouldn’t go so far as to call it comfortable, either. On my 7 inch wrist, at least, YMMV.
I mentioned the Timex Q and M79 above, and one thing Tissot got very much right with the PRX that Timex didn’t with the M79, is not compromising on thickness for the automatic movement. The PRX is within a single mm of the thickness of the quartz model, and even at 11.2 this is a pleasantly svelte watch. Where the M79 ballooned up to 14.4mm from the 11mm of the Q, Tissot kept things in check and I’m glad they did. One thing I’d like to see Tissot adopt from Timex, is their willingness to have a little fun with the colors. The PRX is a comparatively sober affair, despite the lasers and neon colors of the ads. Sure, the black, navy and white dials will stand the test of time, but is this a watch that’s meant to be in the running for single-watch collection status? The case and bracelet place the watch in a very certain era, and I’d like to see the dial take more chances.
The dial of the Powermatic 80 PRX does have one feature not shared by the quartz variant, and that is the ‘Clous De Paris’ dial. Yes, it looks a bit like the Audemars Piguet’s Tapisserie dials given the evenly spaced squares that make up the pattern, but it’s shallow and doesn’t kick out as much light as the AP. It doesn’t hinder legibility, and adds more of a subtle plaid-ish look at a glance. I’d argue it probably doesn’t need to be there, and that if they wanted to spruce up the dial a simple vertical brush would have sufficed, and kept the watch in more original territory. The flat dials on the quartz models looked great in my opinion, while the pattern may not be for everyone.
