Black Bay 36
The 36mm Black Bay introduced in 2016 — Tudor’s smallest dive-watch reference, sized closer to a mid-century field watch than to the 39mm BB58 or the 41mm Black Bay. The T600 caliber (ETA 2824-2 base) keeps the price at the family’s entry band; the line is the Tudor a smaller-wrist buyer cross-shops against the Longines Heritage Diver and Mido Ocean Star 36.
