Freshly refurbished by Swiss Time Services in 2026 and presented with a complete Omega set, it’s a watch that doesn’t just tell the time — it tells a story of care, craftsmanship, and timeless style.

Beautiful 1998 Omega Seamaster 120M Ladies – Reference 2581.81
This is a superb example of the classic Seamaster 120M Ladies, presented with its full Omega box set and freshly refurbished by Swiss Time Services (STS) in April 2026. The watch benefits from a brand-new Omega crystal, crown, clasp, battery and seals, and has been fully pressure-tested with documented results. Timekeeping and functions operate correctly.
The blue wave dial remains the standout feature of this reference, displaying excellent colour and clarity. The stainless steel case and bracelet show only incredibly light, age-appropriate handling marks visible only under close magnification using a jeweller’s loupe. Overall presentation is exceptional for a 1990s example.
This Seamaster comes complete with its Omega presentation box, outer box, operating instructions, card holder, STS service card, COA, Watch Register certificate and original removed parts (excluding clasp). A well-documented, low-risk example ideal for gifting, collecting or daily wear.
