Here is a list of the Polerouters that I've had serviced, where I have an image of the reverse of the dial and which had a Stern dial. Unfortunately I had many more serviced before I realised how useful the information on the reverse of the dial is. I now insist on a photo of the reverse of the dial. I do have many more photos but not all Polerouter dials were made by Stern; many of the early Pola/Polerouter dials were made by Singer and some later dials by Beyeler.

A few points of interest:
- All have the UG client code of 94
- They are in Stern Dial Number order. Apart from one outlier, this also places the watches in UG Serial Number order. I accept that this is a small sample but there is a clear pattern here with later watches having higher Stern Dial Numbers.
- Two of the watches, both gold capped Broad Arrow Polerouters, that are very close in serial number have the same Stern Dial Number
- One of the two dials with the same Stern Dial Number is black (S20214-13) and the other is gold (S20214-14). It is therefore clear that dials with the same Stern Dial Number need not be the same colour.
