Well, I am very happy with buying a solar titanium Bering watch from First Class. I’ve had a Citizen Solar S.S. Chronograph for years but its strap is getting dubiously sloppy. I wanted a slimmer & lighter watch. I found that reviews of citizen showed that solar doesn’t work powerfully enough on smaller diameter watches to reliably operate both date and day functions (which I was hoping for). This meant if I wanted a citizen with 10 ATM swimming I’d have to go again for a chunky lump. This problem seems to apply to all makes. The Bering 15239-777 was the lightest, slimmest & thinnest one with Saphire glass. I found cheaper offers via Skinflint and comparison sites, but taking account of P&P, foreign dealers, and bracelet adjustment, and avoiding continuously varying Amazon pricing (No, it’s not the best value!) First Class watches has proven the best value with everything done/delivered within 24 hours.
