Omega Seamaster Planet Ocean 45.5mm 2900.51.82; Automatic Men's Watch

Description

The Omega Seamaster Planet Ocean 600M with reference number 2900.51.82 is an impressive Swiss sports watch built for serious performance, both above and below water. With its robust construction, professional diving specifications, and recognizable classic Planet Ocean design, this model is one of the most beloved and classic Seamaster Planet Ocean versions.

The substantial 45.5mm case gives the watch a clear 'wrist presence' and emphasizes its professional character. Despite its size, the model wears surprisingly comfortably thanks to the balanced case shape and high-quality finish. This piece comes from 2008 and is in very good condition.

Inside is the high-quality Omega Caliber 2500 Co-Axial automatic movement. This reliable movement runs perfectly and accurately and is known for its excellent performance and solid construction with long service intervals. In this regard, this watch has undergone full servicing in June 2026 at our Omega Certified service center and comes with a service invoice of €592.90 and the luxury Omega Service box.

The watch comes with a comfortable aftermarket rubber strap equipped with a folding clasp (aftermarket calculated; not original Omega). This combination perfectly matches the sporty character of the Planet Ocean and offers high wearing comfort. The strap is suitable for wrists up to approximately 22cm. The Omega rubber strap is also included but is 'worn out'. This strap also comes with the original folding clasp, which unfortunately did not fit this strap, so we are offering it as separate parts (which are still quite handy/useful and have value).

This watch is delivered with nice accessories (see the pictures for what exactly is included); the luxury Omega service box, Omega guarantee cards (2x), hangtag with matching numbers, original Omega strap (worn), and folding clasp, service invoice, and our warranty report with 1 year warranty.
