MONTA OCEANKING CALIBre

Eterna 3909A

COMPARING MOVEMENTS

Finding the right movement for the Oceanking meant looking for something other than the status quo. What it boiled down to was the Eterna 3909A had the competition beat in every meaningful category. The Eterna 3909A beating inside the Oceanking is tuned to COSC standards (-4/+6) and has a power reserve of 65 hours, which is 20 hours better than the average competitor. MONTA offers a 2-year warranty on the movement.

POWER RESERVE AND WINDING

With the 3909A’s weekend-beating 65-hour power reserve, your Oceanking will still be ticking on Monday morning after a weekend of inactivity. What’s more is the reserve couldn’t be easier to fill thanks to the 3909A’s bi-directional winding system. So regardless of your wrist position and movement, your Oceanking will continue to wind.

DURABILITY AND QUALITY

Unlike some parts and products labeled with “Swiss-Made”, the Eterna 3909A is truly made in Switzerland – every gear, screw, plate, wheel and spring. After subjecting the 3909A to rigorous testing, we found its precise and robust build to be the only movement that made sense for the Oceanking.
