The Tudor Black Bay 68 reference M7943A1A0NU introduced a larger 43mm case to the
Black Bay diver line when launched in 2025, splitting the difference between the
brand’s 41mm Black Bay and the 43mm Pelagos in case proportions while retaining 
the heritage-inspired aesthetic that has defined the collection since 2012. The 
43mm stainless steel case measures 13.6mm thick across 22mm lug width, paired with
a unidirectional rotatable bezel finished in stainless steel with a matte black 
aluminum insert and 60-minute diving scale. The domed dial is offered in sun-brushed
silver or blue with applied hour markers, snowflake hands, and Super-LumiNova on
all elements, presenting a refined contemporary execution of Tudor’s vintage Submariner-
inspired design language. Powered by the Tudor Caliber MT5601-U, a Kenissi-manufactured
movement carrying both COSC and METAS Master Chronometer certification, delivering
accuracy of -2/+4 seconds per day, magnetic resistance to 15,000 gauss, and a 70-
hour power reserve at 28,800 vibrations per hour. Water resistant to 200 meters,
fitted on a 22mm three-link stainless steel bracelet with Tudor’s T-fit micro-adjustment
clasp. Marketed as a more substantial alternative to the 41mm Black Bay, the 68 
sits as the contemporary mid-size diver in the Tudor catalog. Pre-owned condition.
