PRODUCT DETAILS
Introducing the first GPS Solar Chronograph within the Prospex collection – the most evolved next-generation chronograph in Seiko history. With a heritage of many world-first achievements in chronograph development, the GPS Solar Speedtimer uses the latest developments in watchmaking to advance the Speedtimer legacy.
Taking inspiration from the renowned 1972 monochrome ‘Panda’ chronograph design, this watch features the same chronograph style as the original, as well as the iconic orange accents.
Under a dual-curved sapphire crystal glass is a dual-time display, high-speed timezone adjustment feature and a time transfer function. Around the perimeter of the white-silver dial, this GPS Solar timepiece enhances the chronograph functionality with the addition of a chronograph scale on the inner bezel. Legibility of the stopwatch function is enhanced by designing the UTC time zone markings on the side of the bezel.
The watch is powered by the in-house 5X83 Solar GPS calibre, with the capability to measure elapsed time through its chronograph feature which can measure elapsed time up to 1/20th of a second. It is accurate to ± 15 seconds per month whilst having a power reserve of 6 months at full charge and can be charged by any light source – either natural sunlight or artificial light – for convenience.
Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.

WATER RESISTANCE
Please check the marking on the back of your watch case and refer to the following table to confirm the degree of water resistance of your watch and the preferable conditions of use. A watch’s water resistance is not permanently guaranteed. It is affected by the ageing of gaskets or deformation of watch parts due to accidental shock. To preserve a watch’s water resistance as long as possible, please follow the precautions below:
- Wipe off moisture, sweat or dirt with a soft dry cloth after removing it from the wrist in order to increase the durability of the case back, gaskets and band.
- After using a water resistant watch in ocean water, wash it in fresh water and dry it with a soft cloth.
- Do not wash a water resistant watch while the crown is pulled out.
- Do not operate the crown or press a button when the watch is wet.
- A periodic overhaul service is recommended to check the water resistance of the watch regularly to ensure it’s functionality.
