It retains the black dial, tachymeter bezel, three-register chronograph layout, and unmistakable Speedmaster design language, but packages them into a more compact \u003cstrong\u003e39mm automatic chronograph\u003c\/strong\u003e with the everyday practicality of a date complication.\u003c\/p\u003e\n\u003cp\u003eThat combination gives the 3513.50 a character quite different from the manually wound 42mm Moonwatch.

The smaller \u003cstrong\u003e39mm case\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003e🌟 COLLECTOR PROVENANCE\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThese 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.\u003c\/p\u003e\n\u003ch2\u003e🧾 FROM THE CASE FILE\u003c\/h2\u003e\n\u003cp\u003eOmega Speedmaster Date Ref. 3513.50.00. 39mm stainless-steel automatic chronograph with black dial, tachymeter bezel, sapphire crystal, date complication, and stainless-steel bracelet.

At 39mm, with automatic winding, a date complication, and the reassurance of a recent full service, this is a particularly practical route into the broader Speedmaster family—and one meant to be worn rather than stored away.\u003c\/p\u003e\n\u003cp\u003e👉 \u003cstrong\u003eEvery case deserves a closer look.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Baker Street Timepieces","offers":[{"title":"Default Title","offer_id":58357397487919,"sku":null,"price":2350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/5359\/5439\/files\/IMG_6237.jpg?v=1787357064","url":"https:\/\/bakerstreettimepieces.com\/products\/case-609-omega-speedmaster-date-black-ref-3513-50-00","provider":"Baker Street Timepieces","version":"1.0","type":"link"}
