2 questions on the 10357-1:
1) Is this a low 1844xxx serial with patented rights pending 215?
2) Is the gold hallmark on the case between the lugs or under the lower right lug?

 

1) Yes and yes
2) Between the lugs

 

Awesome. In that case, this one should have a horizontal gold hallmark between the top lugs.
There seems to be at least 3 hallmark location/position changes through the 10357 serial range.

 

I can check it this evening.

Is mine an early rendition?

 

Yes, definitely. The earliest serial I've seen for a 10357 1 is 1844268, and yours is not far after it.
The earliest production examples (1956-7) had only "Microtor" on the dial and "patented rights pending" stamped on the movement plate around the rotor.
This was whilst they were producing Microtor mechanisms and had applied for the Swiss Patent to protect it, but were waiting for it to be granted (hence they didn't have a patent number yet). It was granted officially as Patent nr. 329805 on 15th May 1958.

Some time around here they switched to "Automatic Microtor" on the dial, and not long after, the 215 movement plates with patented rights pending were replaced with ones stating the swiss patent number instead.
(There is a crossover with the movements, I guess they had an excess of patented rights pending movement plates to use up before switching to the new ones..?)

The same pattern above applies to 20357 (steel version of yours) and 20360 (big case version).

 

Thanks! I've always wondered why my dial only said 'microtor'.

Another thing I found curious, I've owned two microtor UG's and both display poor rotor winding on my wrist. On an automatic winder they show plenty of power reserve.

 

Damn! Show me the back case ..

 

Not sure about that one... some rotors can be a bit "sticky" i've noticed, it might be something to do with the bearing/post that a watchmaker can help with.

 

The watchmaker already checked it and found no issues. I have had the exact same with the other Polerouter. I reckon my less than active office dwelling creates too little motion.

 

Here is my 18k Rose Gold Polerouter DeLuxe - in what I believe is a rather rare Chronometer guise...

 

Thought I'd bump this thread with a few from my ever expanding collection (might be addicted - there are several more that are in for servicing!)


Gold electric 119301-1


A 20361 'Big U' Jet that used to belong to @Jonatan until I could resist no longer


102341 DeLuxe which wears much bigger than the typical Polerouter and stays wound on the wrist better - the bumper movements seem more effective.


10357-1 DeLuxe


860100-01


860100 - 01


My first Polerouter and the one I still enjoy wearing most (though the badly relumed hands are annoying!). 20363-1


20360-2


My latest aquisition, an 869112-03 Super on a too narrow strap!

 

wow @rustynuts that's a helluva bump man. I don't think you have enough yet

Also yours is the only gold electric I've ever seen. Very cool.

 

Dibs!

Love your watch but in the Polerouter Gallery?

 

Eeek! Will delete momentarily if I can - in my excitement thought it was a general UG gallery. SORRY!!!

DONE.
