Kumamoto ™ Bracelet for Tudor Black Bay 58
Inspired by the timeless Rolex Oyster design, the Kumamoto ™ Bracelet brings refined strength and everyday wearability to your Tudor Black Bay 58. Precision-engineered for a seamless fit, this bracelet adds a bold, brushed steel presence to your wrist—without overpowering the clean, understated lines of the case.

It features solid stainless steel links, an elegantly tapered profile (20mm-16mm), and a robust milled clasp with micro-adjustments for a tailored fit. The entire bracelet, end-link and clasp assembly are constructed from high-end, corrosion resistant 316L stainless steel.
