Eco-Drive Solar Movement
The Citizen Promaster Sky AT8300-58L runs on light-powered Eco-Drive technology, converting natural or artificial light into energy so no battery changes are required. It is built for divers and aviators who need reliable timekeeping without maintenance interruptions. The 41.00 mm stainless-steel case and matching bracelet suit daily wear as well as professional use.
200-Metre Water Resistance Under Load
Rated to 200 metres, the watch maintains its seal during prolonged immersion and repeated pressure cycles experienced on extended dives. Sapphire crystal protects the blue dial from scratches that could compromise legibility over time. Solar charging continues while submerged, keeping the chronograph and day-date functions active throughout long sessions.
Check Band Fit and Deployment Clasp
Verify that the fixed stainless-steel bracelet with deployment clasp matches your wrist size, as no alternative strap is included. Confirm the 11.60 mm case thickness clears shirt cuffs and equipment sleeves you wear regularly. Ensure the fixed bezel meets your timing needs, since it does not rotate for elapsed-time tracking.

Questions about this item
Does the 11.60 mm solar case generate noticeable heat on the wrist during long wear?
No — the light-powered quartz movement produces no perceptible heat, so the watch stays comfortable all day.
What strap tool is required to adjust the stainless steel bracelet with its deployment clasp?
A standard spring-bar tool with fine fork tips fits the bracelet end-links and clasp micro-adjust holes for link removal or addition.
Will the 41.00 mm sapphire-crystal case sit flush under tight shirt cuffs designed for slimmer vintage watches?
The 11.60 mm case thickness and domed sapphire crystal add bulk, so very narrow cuffs may catch; test with your tightest sleeve before committing.
