THE REFERENCE LIBRARY

Know what you’re looking at.

Start with the reference. These guides pair manufacturer specifications with practical checks for comparing pre-owned examples.

Submariner

Begin a Submariner comparison with the reference number. Model-family searches can mix watches that need separate price comparisons.

For a Santos comparison, size is part of the identity. A case-width measurement should not be treated as a round watch’s diameter.

The base reference is a starting point. Bracelet and strap configurations still need to be separated before comparing individual Black Bay offers.

Reference research, not inventory. These guides contain no live offers or estimated market prices.
