Catalogue description
Dealer description — Craft & Tailored
The Omega Speedmaster Professional is by far one of our favorite chronographs. The Speedmaster has an incredible history starting with automotive racing, moving into flight, and eventually to NASA and the U.S. Space Program. There are many subtle differences within the vintage Omega Speedmaster range of references that make them all slightly unique and different. The 3592.50 Omega Speedmaster model, also known as the 'De Luxe', is similar to the ‘standard’ Moonwatch reference of the era, the 3570.50, but with a sapphire display case back. In the current Omega collection, you can still find the Speedmaster Professional with a sapphire case back, but it also has the sapphire front crystal, which makes the 3592.50 more unique as it retains the Hesalite crystal on top and the sapphire crystal on the back. Creating a feeling more original to the Moon Watch while offering a window into the beautiful Cal. 863 movement. The 3592.50 was fitted with several movement types, the first being a 17 jewel Cal. 863, which is essentially a more embellished version of the famous workhorse Cal. 861. The Cal. 863 was later upgraded to house 18 jewels and eventually replaced by the later Cal. 1863. The ref. 3592.50 would be a great option for the discerning gentleman looking for a unique yet functional Omega Speedmaster. The Speedmaster looks great on the bracelet as well as a handcrafted leather strap. It is one of our favorite chronographs due to its timeless design and functionality. Its versatility to be paired with the most formal and the most casual of wardrobes also makes the Speedmaster a good choice for the first vintage timepiece and or a classic daily driver.

DIAL & HANDS The matte black dial is flawless, showing no age or damage throughout. The tritium lume plots have achieved a charming creamy patina with no degradation present under UV light inspection. The original tritium hands have aged to a dark grey patina, which is common for Speedmasters in this era. Under UV light inspection, the lume in the minute hand exhibits some superficial cracking and remains stable, with the hour and chronograph hands showing no degradation. ACCESSORIES
Historical context
Mechanical Renaissance (1990 – 2010)
Mechanical watches return as cultural objects; independent watchmaking flourishes.
Mechanical watches returned as cultural and luxury objects. Complications, tourbillons and new materials proliferated; independent watchmakers such as George Daniels, F.P. Journe and Philippe Dufour revived artisanal watchmaking; collecting vintage watches became a major field.

Atlas type guide
Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
