The steel of the case frames a \u003cstrong\u003egold-tone bezel\u003c\/strong\u003e that highlights the dial, creating a refined bi-color interplay. The deep black dial, remarkably understated, catches the light through a cut Crystal.

The inscription “Seiko Quartz” is discreetly placed beneath 12 o'clock.

The term is now commonly used for this elegant rectangular silhouette. This Seiko is not a Cartier, but it captures its spirit in a restrained and accessible Japanese interpretation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the faceted Crystal?\u003c\/strong\u003e\u003cbr\u003eThe faceted Crystal is a mineral crystal whose edges are bevel-cut, creating a subtle play of reflections around the dial. Present on many dress watches of the 1980s, it enhances the sense of depth and the refinement of the piece.

It equipped many of the brand’s dress watches, including a series of rectangular models. Reliable and precise, it requires only periodic battery replacement, to be entrusted to a watchmaker, making it an easy movement to live with day to day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the case made of gold?\u003c\/strong\u003e\u003cbr\u003eThe case is in steel, with a gilded inner bezel (gold-plated) that creates an elegant two-tone contrast. The steel of the case does not present any risk of plating wear and can be repolished. The gilded bezel, however, may show slight traces of wear over time, disclosed here with complete transparency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this watch suitable for a man or a woman?\u003c\/strong\u003e\u003cbr\u003eIt is a unisex piece Unisex.
