Help ID Rolex Precision 18K Ring

[DaveH911]

I was wondering if anyone could tell me about this ring I came across (see photo). I can't seem to find another searching the internet. Unfortunately the crystal is cracked but it still functions. Ser# 872194 and crown engraved on back. Thanks in advance!
