I had in mind, as my second project, a Lucerne Super Flat I sniped off the Bay. Upon stripping it down, I found it was a pin lever movement. Although it would be good practice to service it, I'm on the fence if I want to spend the time, cleaning solution and lubricants on it. In the meantime, I decided to start another project. I bought this Stowa watch four years ago with the idea of getting it serviced. I found that to be cost prohibitive, so it has sat in a box until now.

It wasn't running when I got it and when I opened it up I saw why that might be. There is green and black gunk all over the place. My working theory is that the o-ring disintegrated.

Once some of the gunk came out, it started running! Now I'm a little stuck. This movement is a little different than the Caravelle I worked on first. The second(?) wheel has a friction pinion on the dial side of the movement and I need some advice as to how to remove it. I have a Presto type Bergeon canon pin remover, but it can't get down far enough to work.  I'm also curious curious as to the function of the pinion in question. In addition, there is a spring on the dial side that I'm having trouble removing and wondering if I even need to remove it. The following photo shows the friction pinion on the right and the spring on the left. Any advice would be greatly appreciated.

I just watched Mark's video on the AS 1900 and he did not remove the spring. Also, I gave another try pulling the friction pinion gently with my tweezers. This time it came off and flew across the desk. I feared that it had gone to join so many other parts in that limbo where watch parts and the missing sock from the dryer reside, but I was fortunate enough to find it. So, consider my current problems solved.

I always use my tweezers for the pinions, I use the thicker part behind the tips. It ensures that the part doesn't fly away and preserves the tips! Of course a pinion tool is better and ensures a straight extraction. In any event, good job Don...and you just gave away another hiding place I should search for lost parts! Never thought they would team up with socks! :)

Finally got back to this project today. I removed the mainspring from the barrel and sorted all the parts in the my new cleaning baskets. If I have time tonight I'll run them through the ultrasonic. The mainspring looks good. I was going to replace it, but I think I'll give it a try first.

      Rare Seiko 5actus Watch??!! With a lot🤪🤔😲

      By Kkramme · Posted

      Interesting issue that I just noticed: this Seiko 5actus Watch from 1977 has a calibre listing on the dial of 7019-8030R but on the case back it says 7019-8010!! Like a mis-printed coin, is this watch therefore worth a lot of money for its rarity?? 🤪😲🤔🤪

      I wish that was the case. The Aegler movements used in the early days by Wilsdorf & Davis (for brands like Rolex and Rolco) came in several sizes and without designated calibre numbers that survive.  They become a bit easier to identify during the 1920s. Below is an Aegler-Rebberg, 25.74mm in diameter. It’s from a woman’s Rolex wristwatch. Stamped Rebberg and 500 on the dial plate (but it isn’t a Rebberg 500, it’s the wrong size).  I’d be interested if anyone can identify the movement.  It is based off the Aegler Nr.1, circa 1903, but they based many many calibres of different sizes on it. The closest I have to a positive ID is the  ‘Rolex Nr.50’ circa 1917, but no dial side images or movement sizes are available in the references. There are identical looking movements in many sizes.  The 25.74mm of this movement is a particularly strange size for the era, it equates to 11.41 lignes.      Best Regards, Mark

      FHF70 balance jewels settings

      By GuyMontag · Posted

      It looks like this movement comes with a number of different shock settings. Emmywatch shows that it comes in versions with no shock settings, 'Incabloc', 'shock resist', and 'Supershock'. Perhaps the different settings position the impulse jewel/roller table in a non-ideal position relative to the pallet fork/guard pin. Are you able to check under high magnification if the pallet fork and roller table are able to operate without any interference? Just for fun I took a look and I have one FHF 70 in my collection, a West End Secundus with a non-shock protected FHF70. I had a note with the watch that said, "Movement is stamped 'FHF 70', but the FHF70 looks to have sub-seconds instead of center seconds movement (??)" but that a google search turned up both types for this movement. EDIT: I just took a look in my parts drawer and I have a few of these movements, both in center seconds and sweep seconds, but they all are non-shock protected.

      Sterling fusee info wanted.

      By markr · Posted

      Any info on this watch would help. I know that it's sterling from London but I could not match the o letter date or make out makers mark.  Is the movement maker Camberwell or Lamberwell?   If I give it a twist it will run for about ten seconds.  $45 yard sale find.  I don't think that I want to service a fusee.  What quality is it?
