Not an authenticator by any means, but there are a few things that suggest mid-90s era reproduction. In addition to some really great call-outs in several posts above:
- diamond hour markers would never cover engraving on the dial.
- "T SWISS MADE T" nomenclature was only used in a very short year range in the late 80s to very early 90s, and in all of those vintage models the engraving was outside of the minute ticks rather than inside.
- 12:00 Rolex logo should be offset off the minute ticks either 1) at the same distance that the diamond hour markers are, or 2) aligning the center of mass of the hour markers and the logo. Different years have varying styles of offset
- the round imprint below the 12:00 Rolex logo wouldn't be there
- the toolworking on the engraving on the "superlative chronometer officially certified" looks way too unfinished for Rolex QC
- pearloid/lume inlays on the hour and minute hand are misaligned on the hands, they're usually pushed out nearly to the tips of the hands
edited to add: if I inherited this, I'd wear it shamelessly in my collection. But if the executor is trying to distribute the estate across families by equal approximate value, don't let them value this in the $4-13k range that a blind online appraisal might suggest.
editied to add pt 2: don't laugh that it's scribed as an Oyster sub-model even though the bracelet is obviously jubilee style. Rolex does that too and it makes me laugh.
