Royal Oak Offshore The Beast 25721 — 25721ST · First 100: Royal Oak caseback
1993
The first hundred backs are engraved “Royal Oak” only, without “Offshore” – probably to keep the trademark free in case of failure. The full signature with AP logo was added from no. 100 or 101 (plans of 23 November 1993; sold from January 1994). Examples: no. 32 (sold Italy, December 1993), no. 039 (Gueit’s own).
