The Omega Seamaster Professional 300M GMT, reference 2535.80, is a highly practical and iconic dive watch that combines Omega’s professional underwater credentials with a useful dual-time complication. Part of the classic Seamaster Professional range, this pre-owned luxury watch is presented in very good condition and is offered as watch only, without original box or papers.
Crafted in stainless steel, the 41 mm case offers excellent proportions and comfortable wearability. True to the Seamaster Professional identity, the watch features a blue wave-pattern dial, instantly recognisable and strongly associated with Omega’s maritime heritage. Applied luminous hour markers and skeletonised hands ensure outstanding legibility in low-light and underwater conditions. The additional GMT hand allows the wearer to track a second time zone, making this model particularly appealing for frequent travellers.
The watch is fitted with a blue aluminium unidirectional bezel, designed for precise dive timing while maintaining a classic aesthetic. A sapphire crystal protects the dial, offering strong scratch resistance and long-term clarity.
Powering the watch is the Omega automatic Calibre 2628, a reliable movement equipped with a GMT function and known for its robustness and everyday usability. Designed to meet professional standards, the watch delivers a water resistance of 300 metres, making it suitable for serious diving as well as daily wear.
Completed with a stainless steel bracelet secured by a folding clasp, this Seamaster offers durability, comfort, and a timeless sports-watch character.
This pre-owned Omega Seamaster Professional 300M GMT, reference 2535.80, represents an excellent opportunity to acquire a classic and functional Omega dive watch within the world of pre-owned luxury watches.
