Seiko 5 Sports SRPE58K1 Men's Automatic Two-Tone 40mm Watch. The Seiko SRPE58K1 carries decades of Japanese horological expertise on the wrist. From the 5 Sports collection, the SRPE58K1 measures 40.0mm — comfortably sized for all-day wear without bulk. At 142.0g, you feel it on the wrist — in the best way.. 10 bar (100 metres) water resistance means this can handle the pool, the beach, and everything in between. The stainless steel bracelet with three-fold clasp with secure lock, push button release provides a secure, comfortable fit all day. Multi-function sub-dials display day, date, and more — useful information at a glance. Lume-coated hands and indices keep the time visible in low-light conditions. The 4R36 automatic movement runs on wrist motion alone — no batteries needed, ever. The silver / rose gold tone adds a warm, luxurious accent that catches light beautifully.. Specifications.
