Polarouters Vs Polerouters: 1st, 2nd execution, S and H cases

What is a Polarouter? What is a Polerouter? How to tell the difference, and small changes within the early production period.

What is a Polarouter?

The Polerouter was initially introduced and marketed as a Polarouter in 1954. This can be seen quite clearly within a lot of the early marketing and reference material shown in the Vintage Advertising section. Along with the name being changed to Polerouter in 1955, the case construction was also changed. The original Polarouter case construction can be seen below, where the plexi was was fitted from the inside, then the inner marker ring, and the dial/movement finally pressing everything together for a tight fit. The new Polerouter case construction used a plexi that was press-fitted from the outside, and the marker ring / dial / movement was fitted together as one piece, before being held within the case by clamps.

The Polerouters retained the use of same 138SS caliber bumper movements as their Polarouter predecessors. To reflect the changes, the model reference codes received an S in front of the old ones, changing from, for example,  20217-1 (Polarouter) to S20217-1 (Polerouter). Later in the production period an H-case was also made available (e.g. H20217-1), though the differences between these and S-cases are up for debate. Polarouters can most easily distinguished from later S- and H- Polerouters by the dial, plexi diameter, and the 6-notches in the caseback as opposed to the 12-sided polygonal shape that replaced it on the Polerouter.


Polarouter changes: 1st and 2nd executions

Polarouter serial numbers have been found to range from 1,64x,xxx to 1,69x,xxx, and appear in two distinct serial range batches: (1) 1,64x,xxx; and (2) 1,67x,xxx-1,69x,xxx.


There are also two variants in Polarouter dial types, which correspond with these serial batches. The dial text remains unchanged between the two, however the vertical crosshair line is what distinguishes one type from the other. The First Execution (1,64x,xxx serials) has the vertical crosshair cutting right through the dial text (LEFT, below).  The second execution (1,67x,xxx-1,69x,xxx serials) sees the vertical crosshair line still cut through “Polarouter”, but no longer cut “Universal Geneve”, or “Automatic” (RIGHT, below).


Collectability: 1st Vs 2nd Execution

As Polarouters were only in production for less than a year, the number of both 1st and 2nd executions that we have seen in collections are extremely low. They are rightly amongst the most collectable references in the entire Polarouter/Polerouter model range.  For now, that means there does not seem to be any preference for one execution over another, though that may well change in the future as more examples surface, and collectors tastes and preferences mature.
