I picked this up after a bottle of wine in lockdown on EBay...as you do...for a few dollars. It’s arrived, all working and keeping great time Which was an unexpected bonus. A sweet little thing with some charm to it. I like it.
BUT....what on earth is going on with the bezel?!! I think it’s brass. It rotates easily and fits snugly but I cannot think it’s original to the watch and what is even weirder are where the markings are placed on it. They are engraved but don’t line up...and would not even if it was cut down to fit. Look at top marker...You would expect 30 to be directly opposite. It’s not. And what’s the 55 marker with a circle at top?
Alcohol had input on purchase but could it also be responsible for the wierdest bezel I’ve ever seen! Maybe it’s from an industrial or technical machine - it sure doesn’t belong on any watch I know.
Any thoughts out there? Help a confused watch owner...

Looks like that was made at 4:30PM on a Friday at the bezel factory...

If you rotate it so that the line with the circle is at the top, how well do the rest line up then? 45 and 30 both look to be off by a full 5, but 15 doesn't. Definitely odd. I was just wondering if the arrow was actually supposed to be a the 5.

interesting watch you got there Richard. in addition to the bezel it almost looks like possibly the movement and dial was re-cased? The outer dial markings seem to be partially obscured by the case. Either that or the crystal is ill-fitting and creating the optical illusion?

Def wrong crystal for sure and dial does have outer ring obscured at present.
It’s surely a franken but was about the price of a couple of pizzas delivered so I’m not complaining!

And no none of the Bezel indicators actually line up. I was wondering if it was for a telescope or microscope...

The reason they don't line up is because there's 13 of them, not 12. Presumably this is some kind of fantasy complication created for a particular customer, maybe someone like a therapist who provides 55 minute "hour" session.

Well I popped the back off and it’s got the 17j Enicar which is what I expected. A lot of Leobes use Enicar.
I love the idea that Freud used it for his sessions...brilliant. It’s certainly a curiosity piece.

Enicar? That is a bog stock A Schild 1187 movement with the logo and calibre stamps removed, and the movement marked Enicar.

So what uses 13 in an hour?
or 13 in a circle?

Maybe some sort of telemeter?

am reminded of this one from a modern yema. Look at the scale on the outer edge of dial?

makes sense? there’s M, there’s pi, etc

You can see 17 jewels after a fifth of vodka. Then you make a bezel. ::rimshot::

Not so sure, Enicar used this Type of AS movement and called it AR1010. A bit strange that the AR mark under the balance wheel is missing, but in my eyes it could be a legit Enciar movement. If it is correct in this watch...no idea.

You can put lipstick on a pig, but it is still a pig! Call it Enicar if you like, but it is either an AS 1187 or it’s slightly larger brother, an AS 1194. The Swiss code initials MXL on the balance cock might identify the outfit who marketed it. That code doesn’t show in my reference material.

what is its practical use?
These numbers are laid out logarithmically; you can see that they start at 1.0 and end at 10, and they are laid out so that a constant increment in the angle is a constant multiplier to the value (the distance from 1 to 2 is the same as the distance from 2 to 4 or from 4 to 8). This is the layout one would usually expect in a circular slide rule, and watches with circular slide rule bezels are found in pilot's watches, such as the Breitling Navitimer.

The design of a correct slide-rule bezel would be that the numbers on and adjacent to the rotating bezel are laid out logarithmically so you can multiply and divide by rotating one against the other, see https://www.ablogtowatch.com/how-to-use-a-watch-bezel-slide-rule/ for a primer.

However, this Yema is all screwed up: it has the logarithmic layout, but it doesn't rotate and it would be challenging to use it for anything useful without a second bezel. The product page https://en.yema.com/products/yema-flygraf-heritage-yfly2018 doesn't really trumpet it, and calls it a "Railroad track styled tachymeter scale", which it is not; as far as I can tell, it's just non-functional decoration.
