left: vintage 16800, center: new Batman, right: new Pelagos.
vintage: easy to adjust for multiple fit. easy to clean. pull out for wet suit extension. an old design that still works.
Batman: hard to adjust for 3 slight changes. one link pull out extension, which is too long for my wrist, and probably too short for a wet suit. hard to take apart to clean. pretty machining of the steel.
Pelagos: easy spring loaded three position adjustment and a second spring loaded wet suit extension. hard to clean with all those springs.
pretty matching of the titanium.
changes were made to satisfy market demands, but, IMHO, the classic clasp is still the best. the modern Tudor is better than the modern Batman.
BTW, I've never heard my classic clasp & bracelet rattle.
