TUDOR Black Bay 31 S&G – M79613-0007 Automatic Watch


The Black Bay 31, 36, 39 and 41 models bring a unique aesthetic to the Black Bay line. Their curved cases offer a language that slightly departs from the brand’s iconic tool watch spirit to embrace a sophisticated, versatile, unisex chic.

TUDOR presents a new version of its Black Bay line in steel with a fixed bezel. All fitted with Manufacture Calibres, the models come in four sizes, with a five-link bracelet and clasp with rapid adjustment.

All Black Bay 31/36/39/41 models are available on a five-link bracelet in 316L steel. It comes complete with a robust clasp in 316L steel with TUDOR “T-fit” rapid adjustment system for on the fly size changes. Easy to use, requiring no tools and offering five positions, this practical system allows the wearer to carry out a fine, instant adjustment of up to 8mm on the clasp.
