Two simple technical questions about A10 movement

[Der Amf]

Golly one can end up spending a lot of time reading a lot of confused chatter and uninteresting opinionating about this movement and it's role in the world.

From this link one can download the technical specs for it: http://www.soprod.ch/EN/downloadm.htm

1) is the A10 identical in dimensions to the 2892?
2) is the A10 (unlike, say, the SW300) nonetheless a different design?

If someone who's answered yes to both questions is in a position to muse authoritatively upon the differences between the two movements, then please please please please please

Clearly this thread needs a spurious aviation input from me, so here's a pic of the Fairchild A-10 Thunderbolt, aka the Warthog

There's no need to thank me

Yes, the Soprod A-10 is exactly the same dimensions as the ETA2892/Sw300. Its 3.6mm thick. It also shares a 42hr power reserve.

The Soprod A-10 is a totally different design. However despite that the A-10 (owned by Festina) is not designed by Festina.

The A-10 is in fact a re-badged Seiko 4L25, a movement that was used by Seiko and Credor in their higher ranged models in the last 15yrs or so. The movement is no longer used by Seiko.

I do not know about the technical differences of the movement, but I can say that the A-10 has very much a Grand Seiko movement feel to it (crown use, handwinding etc)

1) No, it's a bit thicker.

2) Yes, it's different to a 2892. By virtue of being based on a Seiko 4L.

Thank you very much.

The A-10 is in fact a re-badged Seiko 4L25. The movement is no longer used by Seiko.

Just to be clear: is it the *design* that is rebadged, or are the actual individual movements using Seiko-built parts?

Erm it has 4 fewer jewels

[Steppy]

Design only - hence it is now Swiss

[Der Amf]

Seiko must have been horrified when they realised they were putting movements only 3.6mm thick into their Grand Seikos. I bet they couldn't flog the design fast enough.

[Steppy]

Don't think they put them into any GS's.

They were limited to the higher range Seiko Auto's and a few of the Credors



Seiko SARA001, 003 and 005

Steppy answered while I was posting. I'll defer to him on the thickness.
