Casio Black Dial Moon Phase Watch, 34mm

A compact Casio moon phase watch with a black dial in a cushion-shaped stainless-steel case, in your choice of stainless-steel mesh or tan leather.

Why It Stands Out

• A real moon phase display at this price, not a printed graphic. The dial tracks where the moon actually is, alongside day and date.
• Three inset sub-dials give the face something to look at instead of an empty black plate, and they all do a job.
• The cushion case is 34mm across and 9.3mm thick, so it has vintage character without turning into a big watch.
• Quartz accuracy of ±20 seconds a month and roughly three years on a battery. You wear it and forget about it.
• Two very different straps on the same watch: mesh for light and dressy, tan leather for warmer and more casual.

Fit and Wear

At 34mm wide and 44.5mm top to bottom this is a small watch by current standards, which is exactly why it works. The 9.3mm case clears a shirt cuff easily and the cushion shape spreads the visual weight so it does not look undersized on a medium wrist. On the mesh it is 80g and slips into place with an adjustable clasp, no tools needed. On the tan leather it warms up and reads casual, better with knitwear and denim than with a suit. The 50 m rating covers rain, a sink and swimming at the surface, though the leather version is happier staying dry.

Colin's Take

The cushion-shaped case and three inset dials give this Casio real character without making it oversized. The mesh keeps it light and dressy. The tan leather warms it up and reads more casual. Same watch underneath, so pick the one that matches the rest of your wrist.
