CITIZEN PROMASTER Introducing the world's first*1 light-powered, satellite GPS diver’s watch. Features world-famous diving locations inscribed on dial ring
Eco Drive Satellite Wave GPS Diver 200m
The new models represent the world’s first light-powered watch with GPS satellite capabilities and 200-meter depth diving function based on the ISO *3 standard. Cal.F158 provides long-lasting power that when fully charged, can continue to operate for about 7 years (in power-saving mode) even without a light source. Satellite signal reception function can be turned off during dive mode by pressing two buttons at 2 and 4 o’clock positions simultaneously. In addition to turning off satellite reception, other functions can also be switched off such as charging and power generation, reception indicator function, power-saving function as well as hands-correction function*4. The dive mode function prioritizes diver safety to prevent erroneous operation and time-critical operations at the push of a button.
Other prominent professional design features and functions include high-visibility luminous indices and watch hands, unidirectional bezel with knurled notches that make operation easy even while wearing diving gloves. Moreover, the watch is equipped with authentic diving watch features such as screw lock crown, sapphire crystal glass, charge capacity display function, and light-level indicator*7.
All functions, except time display, will be ceased to prevent erroneous user time operations at the push of a button. The watch itself is waterproofed to up to 200m, conforming to ISO standard
✓ Turn off charge and power generation confirmation and reception result confirmation functions.
✓ Turn off power save function and hand position correction function.
On the marine blue or emerald green dial, inspired by the ocean of diving spots, luminous large dot indices and thick hands are set to improve visibility. It adopts easy-to-operate unidirectional bezel with knurl, even while wearing diving gloves. The case is made of Super Titanium™, which is feather-light, and resistant to scratches and rust. Finally, the non-slip urethane band comes with an extension band for usage with a wetsuit, and features a wave-motif design.

*1 As an Eco-Drive GPS satellite wave watch. As of January 2020, based on CITIZEN’s internal research.
*2 Eco-Drive is CITIZEN’s proprietary technology that powers watches using any natural or artificial light source, eliminating the need to replace batteries. Certified as an Eco Mark product for the first time in the watch industry. GPS satellite-synchronized watch captures the date and time signals sent by GPS satellites from space — orbiting 20,000 kilometers above the Earth — bringing ultra-precise timekeeping to wherever people are on the face of the globe.
*3 International Organization for Standardization. For ISO, to ensure diver safety, the specifications for divers 'watches are “ISO 6425 divers' watches for diving”.
*4 Hand correction function: Automatic reference position correction function for the hour, minute and second hands. The position of each hand is checked at regular intervals. And if deviation occurs, it is automatically corrected and the correct time is maintained.
*5 Super Titanium™ is CITIZEN’s proprietary technology to treat solid titanium with surface hardening technology. It is at least 5 times harder than stainless steel, resistant to scratches, lightweight and gentle to the skin for comfortable wearing.
*6 Duratect is CITIZEN’s proprietary surface hardening technology that enhances the surface hardness of metals such as stainless steel and titanium, protecting watch bodies from scratches and damage. This technology offers excellent abrasion quality and maintains lustre of metals for long periods of time.
Duratect DLC features smooth texture and glossy lustre, and achieves Vickers hardness of 1,000-1,400 Hv. (Vickers hardness of stainless steel is approximately 200Hv.)
Duratect MRK achieves Vickers hardness of 1,300-1,500 Hv by instilling gas onto the surfaces of titanium materials to harden.
*7 Light-Level Indicator shows how much power the watch is generating through CITIZEN’s proprietary Eco-Drive technology on seven levels by detecting the volume of light the dial is receiving. It can be used as a reference for choosing an ideal charging positions.
*8 As an Eco-Drive GPS satellite wave watch. As of January 2020, based on internal research. In 2015, Citizen realized the world's first Eco-Drive GPS satellite reception watch that receives signals to within 3 seconds.
* The final design and specifications are subject to change without notice.
