With its gentle yet expressive design, it reflects the subtle beauty of Japanese aesthetics and combines this with the unmistakable precision and excellence for which Seiko is recognized worldwide. Now, for the first time, the series is being extended to include watches with a smaller 36mm case - making the SPB521, SPB523 and SPB524 models unisex wearable. Seiko is thus fulfilling the growing desire of many wearers for a midsize dress watch. The structure and color of the dials, inspired by the elegance of Japanese silk, combine various traditional tones and weaving techniques to create a harmonious and artistic aesthetic. For the first time, there is now also a model with a luxurious gold plating.\u003cbr\u003e\u003c\/p\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":44986069647411,"sku":"SPB521","price":995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2495\/1712\/files\/SPB521J1_ima_3_2025.png?v=1791409035","url":"https:\/\/www.caratco.com\/zh-cn\/products\/seiko-presage-classics-series-36mm-spb521","provider":"Carat \u0026 Co.","version":"1.0","type":"link"}
