Solar-powered dress watch
The Citizen Drive CTO BU4020-01L is a 42 mm stainless-steel watch with a blue dial and brown leather strap. Its quartz movement runs on Eco-Drive solar power, so no battery changes are required. The design suits formal and business settings for adult men. Water resistance reaches 100 metres for everyday exposure.
Sustained daily wear
Solar charging keeps the movement running continuously under normal light without intervention. Hardlex crystal resists scratches during long-term use. The fixed bezel and 12 mm case thickness stay comfortable on an 8-inch wrist. Luminous hands and markers remain legible after hours in low light.
Replaces battery quartz models
This watch replaces conventional quartz pieces that need periodic cell swaps. The jump is worth it for owners who want zero maintenance and 100-metre water resistance in a dress profile. Buyers needing a metal bracelet or chronograph functions should look elsewhere.

Questions about this item
Does the solar Eco-Drive movement need a battery change after daily wear?
The Eco-Drive movement converts light into energy, so no battery replacement is required under normal use.
What strap width does the 42 mm case accept if I want a replacement?
The lug width is 22 mm, so any 22 mm strap or bracelet will fit the case.
Will the 12 mm case thickness and 100 m water resistance clear a standard dress-shirt cuff?
At 12 mm thick it slides under most cuffs, and 100 m resistance handles hand-washing and rain without issue.
