# Hermle 140/141 Clock Movement


## Hermle 140/141 Clock Movement

Hermle 140 / 141 Clock Movement comes in either the pendulum or non pendulum styles. Such as the pendulum unit [141-040](/product/new-141-040k-clock-movement-by-hermle) or the non pendulum balance wheel version such as the [140-010](/product/new-150-010-clock-movement-by-hermle).

This is a fourteen day unit, it runs the 14 days on a single wind up. At one time, they were made to run only 8 days. If the numbers are with a 5 instead like 151 or 150-xxx it's an 8 day wind. All they did to make this happen was put a longer mainspring in the barrel.

So if having a 151 or 150 unit, the new unit to replace this is a 141 or 140-xxx instead. The rest of the numbers are consistent with the old. Just match them up.

### The speed

The time from deciding to repair the clock, to having it done, is the very least it could be. It will ship out the next business day, unless its a special gearing. If this is the situation it will take about 4 days to ship as the movement.

This is because the movement comes apart and put together with special gears. You can tell if it is a regear unit if it has an extra charge on the movement that cost more than the rest of the movements. The choice is clear to get the new one instead of overhauling the old unit.

Get the movement in a week or two instead of months later, it will cost about a third the amount of a typical overhaul charge also.
