Citizen has long been a leader in producing dive watches that balance performance, durability, and affordability. The Citizen Promaster 36.5mm Eco-Drive Dive Watch – EO2023-00A is no exception. Compact, stylish, and powered by light, this model is designed for those who want the rugged dependability of a dive watch in a smaller, more versatile size.

At just 36.5mm in diameter, the EO2023-00A is one of the most versatile dive watches in Citizen’s Promaster lineup. Its smaller case size makes it a great option for:

Divers and adventurers with smaller wrists

Women who want a professional dive watch without the oversized look

Everyday wearers who prefer a compact, lightweight design

Why the EO2023-00A Is Special

What makes this Promaster stand out is its blend of performance and wearability. Many dive watches are large, often exceeding 42–44mm, which can feel bulky for some wrists. The EO2023-00A offers professional dive capabilities in a compact package, opening up the Promaster world to a wider audience.

The white dial with bold blue accents adds a fresh, modern look that’s equally stylish on the beach or in the office. It’s proof that dive watches don’t have to be oversized to deliver serious performance.

A durable, versatile design that works for men and women

Comparable Swiss dive watches often cost two to three times more, making Citizen a top choice for affordable, reliable divers.
