The sub-dial is a dead give away.

Also, would one expect to find an enamel dial with a 15.68Z?

 

There are indeed many, correct dial variations but the example that I posted is not one of them.

 

Had never heard of these, but looks a wonderful watch. The discolouration of the dial and numerals work beautifully. Even the 'orange peel' on the dial looks really nice.

 

If it was a metal dial, the sub-dial would be sunken.

 

Wow, learn something new everyday on these forums

 

Here is a picture of my watch, delivered (and confirmed by Longines) in Dec. 1938, movement is a 15.26, engraved no. is 21xx

 

My dial is porcelain or metal?

And what should I think about the lack of inscription on the backcase?

 

The dial that if it exists, would be the most interesting to me is an underline at 6 position.

 

I don't really know these but I seem to recall that Stiocour on MWR who researched them extensively got confirmation from Longines that some civilian ones were also delivered.

 

If you mean unmarked case backs, that is my understanding that there were many sent to military.

 

This apparent underline may not be the result of a distinct dial variant but rather just the application of lume in that location.

 

You’re right, that was what it was.

 

Based on what people have written on MWR Longines did mark some of the case backs themselves.
That was part of Stiocour’s research, he also got evidence about unmarked watches which according to the archives were supplied to the Czech military but had no markings.

From Stiocour on MWR:
« The extract of Longines register for my serial number also mentions the majetek engravings, but strangely enough, they are not stamped on my watch!

May be some were shipped before the engravings were made, or they were possibly erased at a later stage, nobody knows. »

Thanks!

 

I confirm what @Syrte wrote about Longines marking the cases with Majetek (at least for the 15.26 series). These are the records that the wonderful people at Longines provided me with for 2 of my 3 Majeteks (both 15.26 movements). I do not know if they marked or have kept the records for the other series (the 3rd that I have is a 15.68 but I did not specifically ask about the markings).

The order number is XXXXX and I confirm the Majetek engraving.

The order number is XXXXX and I confirm there must be no engraving.

 

Two further pics of mine:

 

Yes - I think you´re right. Thanks for the exploration. Is that red ball made by Longines or later? rgds - h.u.

 

Thank you.
