Omega Seamaster Planet Ocean 45.5mm 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 distinct '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 from 2008 is also in very good condition.

Inside is the high-quality Omega Caliber 2500 Co-Axial automatic movement. This reliable movement runs perfectly and accurately, known for its exceptional performance, robust construction, and long service intervals. Speaking of which, this watch is due for a complete service in June 2026 by our Omega Certified service center, and comes with a service invoice totaling €592.90, along with the luxury Omega service box.

The watch is fitted with a comfortable aftermarket rubber strap featuring a folding clasp (Aftermarket calculated; Not original Omega). This combination matches the sporty character of the Planet Ocean perfectly and offers high wearing comfort. The strap is suitable for wrists up to approximately 22cm. The original Omega rubber strap is also included but is worn out. This strap also comes with the original folding clasp, which unfortunately does not fit this strap, so we are offering it as separate pieces (still useful and valuable).

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