Rolex 722

Probable

The point that governs every vintage Daytona examination: the movement is a Valjoux, not a Rolex design. The correct expectation inside an early Daytona is a Valjoux 72 architecture carrying Rolex signatures and finishing — not a Rolex-specific bridge layout. Examiners who expect the latter reach false findings on correct watches, and the mistake is common because the modern in-house 4130 has trained the opposite intuition.

Architecture

Manually wound column-wheel chronograph on a Valjoux 72 base, finished and adjusted by Rolex.

Service practice

The Valjoux 72 was used across the industry, so generic service parts fit and have circulated for sixty years. A rebuilt 722 containing unsigned generic components runs correctly and is an originality finding rather than an authenticity one.
