The Bulova caliber 82S6 (sometimes incorrectly written as 8S26) is an automatic 3-hander time-only watch movement. This calibre is a true no-date without a phantom date position.

This movement is notably found in the Bulova A-15 Pilot from the brand’s Archive Series, introduced on January 24, 2020.

While the Bulova A-15 Pilot watch has a solid dial, other Bulova models powered by the cal. 82S6 feature an open/skeletonized balance wheel at 7:00.

The caliber used on the A-15 Pilot has an additional reference number at the end, possibly indicating that the watch has a solid dial.

• 82S6-Y1A – Found on the A-15 pilot, without open balance wheel

The full three digit number on other 82S6 powered watches is yet to be confirmed.

Miyota 82XX:

It appears that this movement is actually a Miyota Caliber 82S0. The 82S0 is readily available to brands outside of Citizen, so if you need parts or a replacement, you should be ok with the 82S0.

It is interesting to note that Bulova also has several models using the 82S0, with and without the exposed balance wheel design at 7:00. It is unclear what prompted the change in caliber number to 82S6. Based on stock images, there does not appear to be a difference in finishing, etc.

Hacking Seconds:

Although the current models with the 82S6 are listed as hacking or “hack feature” as Bulova describes it, keep in mind that this movement is based on the 8200 series which originally was a non-hacking caliber. This means that it may be possible for early models to be non-hacking.

Editor’s Note: On second thought, perhaps the switch to 82S6 from 82S0 is an effort to reduce any caliber confusion from the fact that there may be 82S0 watches out there with non-hacking configurations. Further research/exploration is needed to figure this out.
