This 36mm stainless steel watch combines classical Black Bay styling with contemporary refinement. The black dial features diamond hour markers and gold tone hands, protected by a sapphire crystal and offering 100 metres of water resistance. The in-house Manufacture Calibre MT5400 automatic movement provides reliable timekeeping with a substantial power reserve. The watch sits on a stainless steel bracelet fitted with a Tudor T-fit folding clasp and safety catch, making it suitable for both formal and casual wear.
The smaller 36mm case diameter positions this as a more compact entry to the Black Bay collection, appealing to those seeking a refined tool watch without the presence of the larger variants. The diamond markers elevate the dial beyond standard applications, whilst the integrated bracelet and secure clasp system reflect Tudor's attention to finishing and practicality.
