Pre-owned Prospex Speedtimer Automatic Chronograph Srq037 Brand

Seiko Prospex Speedtimer Chronograph SRQ037 BNIB Seiko’s legacy of chronograph expertise inspires a new Speedtimer  The charcoal-gray dialed Speedtimer is inspired from Seiko’s and Japan’s first chronograph wristwatch, the Crown Chronograph from 1964. The 1964 Crown Chronograph was designed from scratch and it marked the beginning of Seiko’s chronograph wristwatch manufacturing. It had a simple one-push mechanism but it amply demonstrated the same commitment to precision as would Caliber 6139 and all its successors with the inclusion of a column wheel to control the start, stop and reset functions.  The new Speedtimer incorporates a new movement from Seiko’s most advanced chronograph 8R series, Caliber 8R46.  Specifications  Caliber Number: 8R46  Movement Type: Automatic with manual winding  Accuracy: +25 to -15 seconds per day  Duration: Approx. 45 hours  Exterior  Case Material: Stainless steel (super hard coating)  Crystal: Dual-curved sapphire crystal  Crystal Coating: Anti-reflective coating on inner sur
