This 31mm bi-metal sports watch combines stainless steel and yellow gold in a refined design suited to smaller wrists. The silver dial features yellow gold hands and diamond hour markers, whilst the fixed bezel is set with diamonds and finished in yellow gold. Water resistant to 100 metres, it sits on a matching stainless steel and yellow gold bracelet secured by a fold-over clasp. The scratch-resistant sapphire crystal protects the dial from daily wear.
The automatic calibre MT5201 movement powers the watch with a 50-hour power reserve, ensuring reliable timekeeping between wind-downs. This Tudor timepiece balances the brand's sporting heritage with precious metal finishing, offering a contemporary take on the Black Bay collection for those preferring a more compact case size.
