This watch from the iconic Presage collection by Seiko is the ultimate expression of Japanese elegance and craftsmanship. Designed for all with its unisex appeal, it strikes the perfect balance between elegant and sophisticated. Its 36.00 mm case diameter pairs beautifully with an optimized thickness of 12.45 mm, delivering unmatched wrist comfort. The case is crafted in stainless steel - durable, hypoallergenic, and ideal for everyday wear. The classic round silhouette is elevated by polished finishes that catch the light in captivating ways. The precisely screwed transparent caseback lets you admire the inner movement in full sophistication.
The dial is a masterclass in subtlety and function. Grey and textured, its finish captures the light, adding brilliant depth to the design. Clear applied indices keep readability front and center, while the minute track adds an extra layer of precision and visual appeal. Elegant analog hands deliver a smooth, accurate reading of hours, minutes, and seconds. A thoughtfully positioned date window rounds out the functionality. Everything is protected by a domed sapphire crystal with anti-reflective coating, ensuring exceptional clarity even in the brightest conditions.
Powering this watch is an impressive automatic movement, the Seiko caliber 6R51. Produced by Seiko Corp, this Japanese movement delivers exceptional reliability, seamlessly blending watchmaking tradition with innovation. Beating at 21,600 vph, it offers remarkable precision. Its 72-hour power reserve means that even after sitting unworn for more than two days, the watch keeps perfect time.
The bracelet lives up to the watch's sophisticated design, crafted in stainless steel with a refined interplay between brushed and polished finishes. This textured harmony gives the watch a modern, distinguished look. It fastens with a silver push-button deployment clasp for easy, secure wear. With a lug width of 18.00 mm, it connects seamlessly to the case for an optimal fit.
With a water resistance rating of 10 ATM, this watch is built to handle the pressure encountered at 100 meters below the surface, making it well-suited for common water sports such as swimming and freediving. This rating goes well beyond splash resistance - it's a genuine mark of durability and robust performance in more demanding aquatic environments.
