{"product_id":"yema-superman-heritage-gmt-39mm-automatic-excellent","title":"Yema Superman Heritage GMT — 39mm Automatic | Excellent","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe in-house movement is the headline. At this price point, having a French-designed and assembled GMT calibre rather than a Sellita or Miyota is a genuine differentiator, and the YEMA3000 backs it up with 42 hours of power reserve and hacking seconds. The fully brushed case gives it a proper tool watch feel, and the bezel-lock at 3 o'clock is a Yema signature going back to 1963 — functional for diving, and a detail you won't find on anything else in this bracket. At 39mm with a 48mm lug-to-lug it wears well on 6.5\"–7.5\" wrists. The 19mm lug width is the one quirk — aftermarket strap options are slightly more limited than the standard 20mm, but it's manageable.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTHE SPECS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eBrand: Yema\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eModel: Superman Heritage GMT Worldtime\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eReference: Superman Heritage GMT\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCase diameter: 39mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCase material: Stainless steel (316L)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDial colour: Black\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMovement: YEMA3000 — Automatic, in-house, 29 jewels, GMT\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWater resistance: 300m (30 bar)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCrystal: Double-domed sapphire\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLug width: 19mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLug-to-lug: 48mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCase thickness: 13.7mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCONDITION\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePre-owned.\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCase: Excellent.
