The Tudor Black Bay Blue made waves when it debuted, offering a contemporary take on vintage Tudor dive watches with a striking blue bezel and dial. Inspired by Tudor’s Submariner heritage, this model bridges the gap between classic tool watch aesthetics and modern reliability, making it a favorite among collectors who appreciate both history and daily wearability. Its 41mm stainless steel case offers strong wrist presence without overwhelming, and the signature snowflake hands nod to Tudor’s late-1960s designs.

Reference 79230B is the key version to look for, powered by Tudor’s in-house MT5602 automatic movement, which brings COSC-certified accuracy and a 70-hour power reserve. Earlier Black Bay models used ETA calibers, but the in-house movement models command higher prices and are more desirable for those seeking the latest technical improvements. The 200m water resistance, screw-down crown, and domed sapphire crystal make it a practical choice for both desk and diving duties.

Price variations depend on bracelet options—steel bracelets are more sought-after than fabric or leather alternatives, and full sets with box and papers consistently fetch premiums. The blue bezel is sometimes compared to the “BB58 Blue,” but the 41mm 79230B offers a chunkier, more substantial feel. When buying, confirm the presence of the correct “rivet” style bracelet if you want the original look, and expect a modest premium for well-kept, unpolished examples.
