Two-Tone Solar Watch with Moonphase

The Citizen Calendrier Moonphase BU0054-52L is a 44 mm men's watch built from two-tone stainless steel with a blue analog dial. It runs on Eco-Drive solar movement Caliber 8730, removing the need for battery changes. The case measures 13.00 mm thick and carries a 100 m water-resistance rating behind mineral crystal.

Replaces Battery Quartz Models

This piece upgrades owners of standard quartz watches who want to stop replacing cells and gain a full calendar plus moonphase in one glance. The jump is worth it when daily convenience, a screw-down case back, and a deployment clasp matter more than a slimmer profile or a higher-spec crystal.

Suits Business and Weekend Wear

Buyers wanting a single solar watch that covers dress codes from office to leisure will find the month, day, date and moonphase layout practical. Shoppers who need sapphire crystal, ISO dive certification, or a lighter titanium case should look at something else.

Questions about this item

What case diameter and lug-to-lug dimensions suit the 44 mm stainless steel case?

The watch has a 44.00 mm case diameter and 13.00 mm thickness; measure your wrist and lug width to confirm a comfortable fit before purchase.

How do I set the month, day, date and moonphase on the Caliber 8730 movement?

Pull the crown to the first position for date, second for day and month, then advance the moonphase indicator using the same crown position sequence.

When should the mineral crystal or deployment clasp be inspected or replaced?

Check the mineral crystal for scratches after impacts and verify the deployment clasp closes securely every few months; replace either part if damage affects water resistance or security.
