I know you’re looking at the 003, but I bought the Sbgn005 last summer. It was very light on the wrist and its blue dial was stunning.
I wasn’t nuts about the 19mm width of the bracelet - for some reason, I didn’t like the way it sat on my wrist. The bracelet overall was adequate, but after wearing Rolex bracelets for so long, adequate didn’t seem good enough, and the clasp lacks micro adjustments.
The lume was also pretty meh, which I found frustrating during a two-week zig-zagging business trip all over the country. The timekeeping was spot-on, however.
I ended up moving it along to a new home about six weeks after purchase. It’s entirely possible I didn’t give it enough of a shot. The finish on the hands and case is wonderful and I’ve thought off and on about grabbing another one to give it another go on the wrist for a more substantial period of time...but not enough to pull the trigger yet.
