Omega Speedmaster Reduced Sapphire ref. 3539.50.00 Full Set Omega Serviced

Info

There are Speedmasters that have shaped the history of the collection. And then there are references that represent its most refined evolution.

The Omega Speedmaster Reduced 3539.50.00 belongs precisely to this latter category. Produced for a very short period during the final years before the definitive discontinuation of the Reduced line, it represents the most technically updated version of this historic 39 mm automatic chronograph.

The most visible change is the transition from hesalite to sapphire crystal. This is not merely an aesthetic upgrade, but a genuine technical evolution: improved scratch resistance, enhanced brilliance, and an overall more modern and solid perception on the wrist.

The dial also underwent subtle yet meaningful refinement. Compared to the hesalite versions, the outer minute track no longer features the printed second numerals, resulting in a cleaner and more contemporary layout. The visual effect is more balanced and legible, with the sapphire crystal enhancing the depth and clarity of the dial.

Produced in significantly lower numbers than earlier versions, this reference is today widely considered the most sought-after Reduced on the market. It represents the final evolutionary chapter of a project that successfully translated the Speedmaster identity into a more compact, versatile, and everyday dimension without compromising its sporty character.

Case, Bracelet, Dial & Glass

General Overview: This 2010 Omega Speedmaster Reduced sapphire crystal reference 3539.50.00 is presented in excellent aesthetic condition, fully consistent with a carefully preserved example. The Omega automatic caliber 3220 has been fully serviced at an authorized Omega service center and shows excellent performance parameters, with strong amplitude and stable behavior in all positions. The watch is perfectly functional and ready to be worn immediately. The set is complete and includes Omega box, original warranty, and accompanying documentation.

Case: The 39 mm stainless steel case retains well-defined lines and harmonious proportions. Polished and brushed surfaces are nicely balanced and show only light micro hairlines visible under close inspection. The black tachymeter bezel remains in very attractive condition, with perfectly legible scale and only minimal micro imperfections along the outer edge. The caseback, featuring the iconic embossed Speedmaster hippocampus, preserves deep engravings and crisp details, including the serial number.

Bracelet: The watch is fitted with the Omega reference 1471 bracelet with 815 end links, consistent with late production examples, and equipped with a deployant clasp featuring push-buttons. The structure feels solid and well-balanced on the wrist. The bracelet shows only slight, natural stretch and fine surface marks visible only upon close inspection. The Omega engraving on the clasp is sharp and well preserved. The bracelet is complete with all original links and fits wrists up to approximately 21.5 cm.

Dial: The black dial stands out for the cleaner layout typical of the sapphire crystal version: the absence of printed second numerals along the outer minute track creates a more orderly and contemporary aesthetic compared to earlier Reduced models. The surface is uniform and deep, with applied indexes and hands in excellent condition. The green Super-LumiNova is fully functional.

Crystal: The sapphire crystal is clear and free from scratches. Its transparency enhances the depth of the dial and further confirms the overall excellent state of preservation of the timepiece.
