Omega Seamaster Professional 300M – Ref. 2561.80.00 (1990s) 

Automatic | Blue Wave Dial | 36mm | Stainless Steel 

A true modern-classic from Omega, this Seamaster Professional 300M dates to the mid-1990s and represents one of the most important dive-watch designs of the era.

The reference 2561.80.00 features the iconic blue wave dial, sword hands, helium escape valve, and a slim, highly wearable 36mm case—often referred to as the “mid-size” but, in reality, perfect for everyday wear.

This example stands out thanks to its honest natural patina to the tritium indices, giving the watch real warmth and character that collectors actively look for. Nothing forced, nothing overdone—just time doing its thing.

Historical Context

The Seamaster Professional 300M rose to global prominence in the 1990s and became synonymous with Omega’s resurgence as a serious tool-watch brand.

This exact blue wave Seamaster is widely referenced as part of the same family of watches associated with Princess Diana in the mid-1990s, and later linked in press and collector circles to Prince William. While provenance pieces command huge premiums, the design itself remains one of the most recognisable and culturally significant Omega sports watches ever made.
