The case for it

Wave dial, ceramic bezel, display back and Master Chronometer movement make the current Diver 300M a complete modern sports watch rather than a nostalgia exercise.

What goes wrong

Supply is healthy. Bracelet scratches, missing links, warranty, complete accessories and pricing too close to retail explain most weak transactions.

Who it fits

Best for someone who wants a modern daily diver with strong service support and more technical identity than a minimalist sports watch.
