The SPB529J is the first leather-strap limited edition in the Presage Classic Series, showcasing refined “Shiracha” tones—a deep brown paired with a smoky dial gradation. Its mirror-finished brown ion-plated case and knurled edge accentuate the vintage-inspired design, while the strap, crafted from upcycled leather by a historic shoe manufacturer, reflects a commitment to the Sustainable Development Goals (SDGs) by reducing waste. Powered by Calibre 6R55, the watch offers 100M water resistance, a 40.2mm case, a screw see-through case back, and a three-fold clasp. Limited to 3,000 pieces worldwide, it celebrates sustainable craftsmanship and timeless Japanese design. - Automatic Movement – Powered by the movement of the wearer - Caliber 6R55 - Accuracy: +25 -15 seconds a day at normal temperature range (5°C and 35°C) - 72 Hours Power Reserve - 40.2mm Case Size - 13mm Case Thickness - Stainless Steel Case - Upcycled Leather Strap - Dual Curved Sapphire Glass with Anti-Reflective Coating on the Inside - Pull Out Crown - 100 Meters Water Resistant
