The ONOLA 3838 (ON3838) is a men's automatic watch with a tonneau-shaped alloy case and an open dial that shows the skeleton gear train underneath. Hardlex glass covers the 51mm face, and the watch winds itself with wrist motion.
Open gear dial You can watch the automatic movement turn through the skeleton dial, without ever needing to wind it by hand.
Scratch-resistant glass Hardlex crystal glass holds up to daily knocks better than standard glass, keeping the view clear.
Secure fit A silicon strap with a bracelet clasp adjusts to 250mm, and 30M water resistance covers splashes and rain, not swimming or showering.
