It disappears under any cuff – and that's exactly what it was made for.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eClassification\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe first half of the 1980s was the era when quartz technology truly delivered on its design potential. With no mainspring, balance wheel, or oscillating weight taking up space, cases could become as thin as mechanics had never allowed. Seiko pushed this boundary particularly far during this time, and the small rectangular dress models are the purest form of this innovation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis particular watch operates with the caliber 9021.

The hands are equally understated, and a second hand is intentionally absent. The result is a watch that barely stands out as a timepiece on the wrist, but rather acts as a piece of jewelry.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe square case with softly rounded corners measures 25.6 × 28.3 mm with a lug-to-lug distance of 35 mm. The watch comes with a new brown leather strap with lizard embossing, which complements the warm gold tone.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eRegarding case material:\u003c\/strong\u003e The case back is stainless steel, and the case itself is gold-plated base metal. This is the common construction for small dress quartz watches of these years and is appropriately marked on the case back. We expressly point this out to ensure clarity regarding the material specification from the outset. \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eCondition\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe watch is in very good condition and appears very high-quality.
