Reference 2900.50.91. A sheet to take with you: the numbers to check the watch against, what to look at, and what to ask. It does not authenticate anything and it does not tell you whether to buy.
Measure or ask. A watch that does not match these is not necessarily wrong, but it is a question worth the answer.

Anything above marked not recorded is a gap in this catalog, not a property of the watch. Do not read a blank as a zero.
This catalog has no authentication guide for 2900.50.91 yet, so this sheet cannot tell you what correct looks like on this specific watch. The general inspection checklist and the counterfeit awareness guide still apply, and the numbers above are worth checking either way.
The specifications above are sourced to omegawatches.com, monochrome-watches.com. What else the catalog does not know.
