Proving that high-performance timekeeping can be incredibly stylish, the Grand Seiko Sport collection will allow you to enjoy expert precision and striking aesthetics.

The first ever Grand Seiko chronograph, this Grand Seiko Sport watch is presented in a striking 40mm stainless steel case and protected by sapphire crystal glass.

Powered by a unique Spring Drive movement, the black dial is equipped with a 24-hour hand, three chronograph sub-dials, a date display window, and a power reserve indicator.

Presented on a stainless steel bracelet with a three-fold clasp, this luxurious model is water resistant to 100 meters and offers a 72-hour power reserve. This high-performance model benefits from a ready/start button with a half-press shutter, allowing for accurate starts and enhanced precision.

Calibre 9R86:

Spring Drive Calibre 9R86 may well be the world's most accurate spring-driven chronograph. It delivers a precision of ±15 seconds a month, or ±1 second a day and, equally importantly, measures elapsed time not to the nearest fraction of a second but exactly, thanks to the fact that the glide motion hands stop at the very instant that the button is pressed.
The 72 hour power reserve is maintained even if the chronograph is in operation.

Processing Timelines and Inventory Availability

Our Rigorous Pre-Shipment Process

To ensure absolute accuracy and quality, every timepiece undergoes a strict, multi-stage preparation protocol before leaving our facility:

  1. Verification and Set Assembly: The watch is removed from our secure showcase and cross-referenced against its specific web listing. Our inventory team compiles the exact factory box, user manuals, serial hang tags, and original warranty documentation to guarantee the full kit perfectly matches our description.
  2. Horological Diagnostic Testing: The timepiece is passed to our expert team of watchmakers for final operational diagnostics. Using state-of-the-art diagnostic equipment, our team runs a comprehensive series of checks to verify correct cosmetic condition, timing and amplitude accuracy, and water resistance parameters (where applicable), ensuring the watch performs to factory standards.

Shipment and Secure Delivery Protocols

Once cleared by our watchmaking team, your order moves into our high-security packing and dispatch phase:

  • Premium Couriers: All orders are securely packaged using tamper-evident materials and dispatched via our trusted logistics partners, FedEx or UPS.
  • Address Verification: To safeguard your high-value asset against interception and digital identity theft, orders are standardly shipped exclusively to your verified billing address.
