WATCH RITUALFor most people, the 40 mm Powermatic 80. We would choose ice blue if it is your only watch and black if you want it to go with everything. Choose the 35 mm for wrists under about 6.75 inches, and the quartz if you want the look for about half the price.

The Powermatic 80 automatic winds itself as you wear it, runs for a rated 80 hours off the wrist, and shows its movement through a see-through caseback. The quartz never needs winding, is slimmer at 10.4 mm, and costs about half as much. Both have sapphire and 100 m water resistance. If the movement is part of why you want a Swiss watch, buy the automatic; if you want the PRX design, the quartz is the smart buy. PRX automatic vs quartz, compared.
The case, bracelet and dial read as one shape, so the PRX can look larger than its numbers. Under about 6.75 inches, we would start with the 35 mm; above that, the 40 mm. Both are 10.93 mm thick in the automatic. PRX 35 mm vs 40 mm.
Ice blue is the most distinctive and the one buyers come back to. Black is the most versatile. Blue sits between the two. Green and light green add colour, and the gold-tone champagne is an occasion watch. Blue vs ice blue · Black vs blue · Gold vs steel.
