Default 61## main plates ?

I have just disassembled a 6106-6003 to find an unusual main plate...to me that is. Having disassembled a few 61## (A, B & C) movements this one took me by surprise. It's a 6106C movement with 4 diafix jewels and one very odd crimped jewel.

I checked the relative parts catalogues and non show the main frame or for that matter provide part numbers.

Does anyone know the frame part numbers for, 6106 and 6119 movements, A B and C options. I would like to know where in the chain this version falls.

It looks like a watch makers upgrade. That crimped jewel I've not seen yet though.

Possibly but I viewed them at x15 and all look pre plated machined ports with no post plate machining or watchmakers leftovers. Clearly the diashock has been visited.

The dial states 25 jewels but I can only count 23 which includes end caps and stones. This shortage has been discussed elsewhere but I cannot recall why.

The day/date dial is EQ which I think is English/Qatar(Arabic) but stand corrected.

That crimped jewel is actually a diafix pair - a hole jewel with a cap. The other missing jewel is likely in the pawl lever. Replacement parts for the diafix pair also show the odd crimping, but not all C's seem to have it.
