Status: Active Investigation
Condition: Good Pre-Owned
Scope: Watch Only with Presentation Box
Year: Unknown
Service: Recent Full Service

🔎 CASE NOTES

The Omega Speedmaster Date Ref. 3513.50 occupies a particularly useful place within the Speedmaster family. It retains the black dial, tachymeter bezel, three-register chronograph layout, and unmistakable Speedmaster design language, but packages them into a more compact 39mm automatic chronograph with the everyday practicality of a date complication.

That combination gives the 3513.50 a character quite different from the manually wound 42mm Moonwatch. It's smaller, automatic, and arguably easier to live with as a daily watch, while remaining immediately recognizable as a Speedmaster.

Case #609 is presented in good pre-owned condition, showing wear consistent with previous use. Of particular importance, the watch has undergone a recent full service, adding meaningful reassurance to an older automatic chronograph.

The watch is offered watch only with a presentation box and is currently sized for approximately a 6.5–6.75-inch wrist.

The 3513.50 is a 39mm automatic Speedmaster Date powered by Omega's Calibre 1152 and equipped with a sapphire crystal, chronograph, tachymeter, and date complication.

Condition Notes: Good pre-owned condition with signs of wear consistent with previous use. Please review photographs carefully for the complete cosmetic condition.

⚙️ THE EVERYDAY SPEEDMASTER

The automatic movement and date complication distinguish the 3513.50 from the traditional Moonwatch formula. The smaller 39mm case also gives it considerably more compact proportions, making this generation particularly appealing to collectors who find the Professional oversized for their wrist or simply prefer a more understated chronograph.

The recent full service is particularly relevant here. With an older automatic chronograph, known recent mechanical attention can be every bit as important as cosmetic condition.

🌟 COLLECTOR PROVENANCE

The 3513.50 comes from an interesting period in Omega's history when the Speedmaster family extended well beyond the Professional Moonwatch into smaller automatic chronographs designed for everyday wear.

These references have developed their own following precisely because they aren't simply scaled-down Moonwatches. The automatic movement, date window, polished details, and compact proportions create a distinctly late-1990s/2000s Omega personality that is increasingly recognizable in its own right.
