【Limited to 1,300 pieces (200 in Japan)】 SBDX053 SEIKO Prospex Diver Scuba Save The Ocean Limited Edition. Retail price: ¥385,000 Brand new, unused, with all accessories included. The label on the back cover has not been removed. Purchased in November 2025, with a full 3-year warranty remaining. Navy diver's watch, 200m water resistance, limited edition. The dial design motif is the "Astrolabe," an astronomical instrument used for navigation since ancient times. The astrolabe, one of the artifacts unearthed from underwater archaeological sites, could determine the latitude and time of the current location from the position of stars and the sun, supporting adventurers of the time. It is a special dial design that evokes the history of ancient knowledge and the challenges of adventurers. The case design is a modern interpretation of the original model's classic design. By applying Zaratsu polishing to the sides of the case and the outer circumference of the rotating bezel, the distortion-free mirror surface given to the heritage design emits a beautiful shine. The strap uses reinforced silicone with a striped pattern. In addition to the dual-curved sapphire glass with an anti-reflective coating on the inner surface, the Lumibrite applied to the indexes and hour, minute, and second hands ensures high visibility in all environments. - Model: PROSPEX Limited Edition - Color: Navy - Water resistance: 200m - Serial number: 1088/1300 - Accessories: Dedicated box Caliber No: 8L35 Driving system: Mechanical (automatic winding with manual winding) Accuracy: +15 seconds to -10 seconds per day Driving period: Approximately 50 hours at maximum winding Number of jewels: 26 jewels Functions: Vibration frequency: 28,800 vibrations/hour (8 vibrations/second) Second hand stop function: Calendar (date) function Case material: Stainless steel case coating Dia Shield Case size Thickness: 13.1mm Width: 41.3mm Length: 47.6mm Glass material: Dual-curved sapphire Lumibrite #First Diver #1st #SEIKO #SBEN003 #SBDX039 #150m #Men's #Watch #Wristwatch (analog) #prospex #Diver's watch #DIVER #PROSPEX #LIMITED EDITION #Limited edition #Rare #Limited quantity #Deadstock
