In this case my two other divers at present are Tudor BB58 blue (longest tenured piece) and Longines Legend Diver 39 mm green. Lately I’m feeling a bit bored with those two, so it may be time for a change. If I get the green SMP, I may keep the BB58 blue. Seems to be the most logical choice. If I got the blue SMP, the blue BB58 would then be redundant so less likely to stay. At the moment, its possible I’d flip both of the current divers in my collection and be very pleased with either color SMP. We’ll see… 🙂
That Sinn you mentioned is a very attractive shade of green. At one point I owned the Sinn 556 blue and emerald. Divers are much more my thing at this stage of the game versus chronographs or time only.
Rolex Sub is not a consideration, for me personally it’s silly to spend that much, also, think the Omega is much more attractive
