🔎 Case Notes

The Tudor Black Bay Fifty-Eight “Navy Blue” Ref. M79030B is one of the most balanced and widely admired modern Tudor references — a watch that channels the proportions and spirit of the mid-20th-century divers while bringing in a cool, contemporary navy tone that quickly became a fan favorite.

With its 39mm case, slim profile, and matte blue dial/bezel pairing, the BB58 Blue wears comfortably on nearly any wrist. Tudor’s in-house movement offers modern robustness inside, while the gilt-free blue aesthetic gives the watch a clean, crisp, and deeply versatile presence. This is a diver that feels at home everywhere — from desk to shore to weekend rotation.

This example is in good pre-owned condition, showing light, natural signs of honest use across the bracelet and case. The bezel, dial, and crystal remain clean and bright, and the overall presentation is strong. The watch includes its complete full kit, adding confidence and collectability.

The Blue is often considered the most approachable and universal of the BB58 line.
