What distinguishes it
Look beyond the reference.
A 4 Hz oscillator and approximately 70-hour reserve combine a familiar modern beat rate with enough running time for an unworn weekend when fully wound. Tudor’s specification identifies a silicon balance spring and a bridge supporting the variable-inertia balance.
For the enthusiast
This entry covers MT5602 as documented for the Heritage Black Bay. Later Black Bay references can use movements such as MT5602-U; their certification and detailed specifications should be checked separately. The shared Black Bay name is a collection identity, not proof that two watches contain the same calibre.
