Why consider it

Light-powered operation, radio synchronization and world time suit someone who enjoys setting up useful watch functions. The blue bezel and dark bracelet make the design as assertive as the feature list.

The tradeoff

At 44.5 mm, this is a substantial watch. Radio reception depends on location and conditions; read the operating instructions rather than expecting automatic correction everywhere.

THE ESSENTIALS
