Help To ID early Swiss 12 L movement "Click" to Login or Register

Recently acquire this watch, Sterling silver with three bears British Import marks tells me it was made prior to 1907 in Switzerland for import to England. Was made into a WW at sometime. Case is very good quality and quite heavy and sturdy. Marked .935.
Watch has very nice quality movement. I have not taken it apart but cannot find any ID marks, Does have a couple numerical marks on it. You will note the Wolf Teeth and presence of the end caps. Would appear it might have had a Geneva Stop Work fitted at some time. Has bimetallic balance with Breguet hairspring.
It is fitted with a pressed on dial (no feet) sans seconds chapter. A ring surrounding the dial has tiny slots at the 12 and 3 positions. This arrangement allows the movement to be used as either an open or hunter movement.
Movement runs but need service. Would appreciate any help you may have.

Another: you can see where a Geneva stop works may have been fitted but see no evidence it ever was.

Hi Enrico; Thank you for the information. Any more info.? Cal. no. etc. Do you know if they used the "switchable" dial on other movements? Thanks again, John

I'm sorry but I do not know the exact caliber. Lecoultre has over 1000 different calibers. The snaps on dial , and wolf teeth were reserved for high grade caliber.
regards enrico

Hi: Not sure if anyone will see this but I need some advice here. After cleaning this watch it is not carrying the hands properly. (Did so prior to cleaning).It has an arbour that fits through the center wheel (center wheel staff is hollow) which then holds the cannon pinion. I am not sure where the friction is at play. It makes sense to me that it would be between the center arbour and the center staff as opposed to between the Cannon pinion and the center arbour. If this is so how does one correct the loss of friction at this point. Hope this makes a little sense to someone. Thank you

I just finished one with the same type of cannon pinion type you have..all you have to do istap the cannon pinion down against the shoulder of the sleeve that the pin runs through .the back part of the pin with the square head on it must be on something solid under it and the cannon pinion facing up..then gently tap the cannon pinion down so it makes contact and pressure on the sleeve that the gear is held in place with..do it gently and then turn the square head on the back to see how much resistance there is..you have to be carefull not to put to much resistance on it, because if you do, you can break of the teeth of the setting gears when you try to set the time..so basically you have to tighten the fit of the cannon pinion to the small shaft with the square head on it..
