Restoration: Marti Watch with Standard/AS 1686 Movement

I got this watch in a batch and decided to restore it. Marti is a jeweler’s brand from Amsterdam, and the movement is a Standard/ AS 1686 with 17 jewels. The watch had a terrible crystal, a dirty dial, and the movement was dry and full of debris as well. It ran irregularly with a low amplitude.

Marti watch. The damaged crystal and dirty dial are immediately apparent.


As always, I start by removing the balance and the pallets.

The tiny pieces of debris and dust particles are visible.

Then I flip it to the dial side to remove the motion works and the keyless works.

All stripped except for the end stones and the set lever. Interestingly, the 3rd wheel has received an endstone on the baseplate but not on the wheel train bridge.

Flip it back again and start with removing the wheel train bridge.

Here you can see the sweep-second wheel, third wheel, and the escape wheel.

After you’ve removed the sweep-second wheel, third wheel and the escape wheel, the center-wheel cock, and the center-wheel are left.

Center-wheel cock and the center-wheel left.

After this step, I remove the center-wheel cock, but I can’t immediately remove the center-wheel. To be able to do this, first, the ratchet wheel has to be removed.

You can see that the center-wheel runs underneath the ratchet wheel.

I removed the ratchet wheel and the crown wheel. Then I lifted the barrel bridge, the center-wheel, and finally the main barrel. I use a peg wood to pre-clean everything before I clean everything in the watch cleaning machine. Take extra care in cleaning the bearing jewels and the pallets.


As always, I begin with the main barrel and then the wheel train. Before the wheels are replaced, I have to fit the end stones on the dial side again. I lubricate them with a tiny bit of Moebius 9010. The center-wheel first, then the center-wheel cock and the escape wheel. The other two wheels follow.

Main barrel, center-wheel, and center-wheel cock and escape wheel installed.

Remember to fit the barrel bridge and ratchet wheel back first before you reinstall the third wheel and the sweep-second wheel.

Just before replacing the third wheel and sweep-second wheel.

I refitted the crown wheel, third wheel, and sweep-second wheel and reinstalled the wheel train bridge.

I turn the movement to install the motion work and the keyless works.

The keyless works installed and the motion works too, except for the hour wheel.

I flip the movement to reinstall the pallets, pallet cock, and the balance.

Finished, recased, and ticking happily again.

I refitted the dial and hands. I also installed a new crystal with a steel-colored tension ring. This Marti watch can be enjoyed for years to come.
