Just Watch Jona men's watch 42 mm blue leather strap

The Jona starts with a stainless steel case in a silver colour, 42 mm across and 11 mm thick, fitted with a mineral glass. Inside is a quartz movement, and the round blue dial shows the time in analogue style. It is a men's watch from Just Watch, and it belongs to our range of men's leather strap watches.

Dial and functions

The dial is blue with silver baton markers, so the layout stays clean and easy to read. A date window sits on the dial. The hands and the hour markers are luminescent, which means they glow in the dark once they have been exposed to light.

Movement

The quartz movement keeps steady time with no winding. When the battery runs low, have it changed by a watchmaker, who can also check the seals while the case is open.

Case and water resistance

At 42 mm, the case is a standard size for a man's wrist, and 11 mm of thickness keeps it from feeling bulky. Water resistance is rated at 5 ATM. That covers rain, splashes and hand washing. For swimming, take it off.

Strap and clasp

The blue leather strap closes with a pin buckle and is 22 mm wide between the lugs, which is the figure to note if you ever want a replacement. Total length is 23.5 cm. Leather softens and develops character with wear, so keep it away from water to make it last.

With its leather strap and plain dial, the Jona sits comfortably with a shirt or a suit, and it is discreet enough to forget on your wrist through a normal day.
