I totally agree but the Stern lead could at least prove that it's definitely wrong, if for example the dial proved to be much later. I'm only following up on the clues that are available to me.
A connection with SAS is going to be very difficult, if not impossible, to prove because of the lack of records. What I really need is to see the reverse of other Polarouter dials as they could provide some useful clues. For example:
- Do non-SAS black dialled Polarouters have Stern dials? If not, that would seem to increase the likelihood of this being a special bespoke dial rather than a redialled Polarouter dial.
- Do the white dialled SAS Polarouters have Stern dials? If not, then that wouldn't necessarily prove anything but if they do have Stern dials and the order number is close to mine then that would seem to increase the likelihood that the dial is genuine.
Are there any known examples of a case reference 20217-4 that do not have Polarouter printed on the dial?
I think the "Pola" vs. "Pole" has more to do with the production date of the watch than the reference number.
The reason why the dial is black on the reverse is apparently because it was galvanised. This is also why the front of the dial is very glossy and has survived well because a layer of lacquer is typically applied to the front after the galvanising process.
I'm still hoping to date the dial itself although that is unlikely to answer the key question of who applied the SAS logo and text and when it was done.
Galvanising protects steel or iron from rust. The process involves dipping iron or steel in zinc. Dials are usually made of brass, silver and rarely in more expensive watches, gold plated or gold (which does not rust). Galvanising leaves a silverish tint, not black. Additionally that dial shows what looks like a blob of paint ...
It is definitely not galvanised or anodized come to that (only used on ally) ....
Sorry to be so skeptic about it but it does not convince me in any way. The very least I would expect from a redial, is centering !
Apart from all of that, you seem to be convinced and I admire your persistence. However, in my eyes it is mutton dressed as lamb (old english saying).
