Original and New Old Stock spare part for BUREN Chronomatic Cal.12 / 14 / 15 automatic movement, used by Heuer, Hamilton, Breitling and other brands for their automatic chronographs of '70.

The part ref. is 8086 oscillating pinion, the auction is for one (1) piece.

This part is suitable for Cal11 / 11i variants too even if the early Cal11 movement had originally the bimetallic pinion (brass + steel), this all-steel pinion in auction is obviously more robust than the brass one.

We have many other parts available not listed for this movement so feel free to contact us in case you are looking for other parts.

If you buy other parts (see other available parts) we can combine shipping in order to pay only a single shipping cost (please specify this by email).
