This 39mm stainless steel watch represents the contemporary iteration of Tudor's Black Bay collection. The blue dial features applied stainless steel hands and diamond hour markers beneath a flat sapphire crystal. The case and bezel combine polished and satin finishes, whilst the screw-down crown bears the Tudor rose relief. Water resistance extends to 100 metres, suitable for swimming and snorkelling but not diving. The watch is fitted with a stainless steel bracelet in matching polished and satin finishes, secured by a Tudor T-fit folding clasp with safety catch.
The movement is the in-house Manufacture Calibre MT5602, an automatic mechanism with bidirectional rotor system. The movement carries COSC chronometer certification, confirming accuracy standards. The 39mm case diameter positions this as a moderately sized sports watch, appropriate for varied wrist sizes whilst maintaining the proportion and presence associated with the Black Bay line.
