There are a lot of good brands in the marketplace at various pricepoints.
I currently own 5 premium watches. All of which are very good servicable watches. With a few exceptions, all the major watch companies use the same basic guts (movement) for the watch. They provide a unique case, face and, watch band.
For absolute clarity and ease of reading the TIME, diver style watches and some aviation oriented watches rule. Chrono's add distraction to the face and, I rarely use mine. So, at this point in time I find myself moving away from the complicated (and more expensive) watches.
Fortis is a watch brand that doesn't catch much press or nice flashy television spots but, that helps keep the prices down on a high quality "tool" watch. No, it probably won't impress your friends or coworkers who can spot a Rolex or James Bond watch from 100 feet away but, it will serve you well and take a softer bite out of your wallet.
Limes is a brand that few have heard of. You might want to checkout their NightFlight 2 series. Very good watches and good prices too.
Limes
If I'm not mistaken the Sinn 656 has an acrylic and slightly convex face cover. Acrylic will scratch easier but, can be buffed out. Also, Sinn in general has no corporate identity in the USA. This may have changed since I last time I checked.
I consider Sinn, Tutima and, Revue Thommen to all be comarable watch lines. Tutima has the strongest retail prescence of the three but, I find my taste best met by the Revue Thommen line. Those RT Airspeeds are sweet
.
When you know what type of type of watch you want (simple or complicated/Chrono), determine the size (40+mm or ~34mm), determine face color (why can't you buy a black face with a black date wheen with white lettering
from the factory) and, then compare the brands, you may find yourself looking at a different companies watch line.
Have fun with your search!
