  1. I am responding to myself. Dennis Bacon (pseudonym 'Max Cutmore') offered the following advice on his Pocket Watch Handbook: Mr. Bacon seemed to disagree with this option:
  2. Hi Frank, many thanks for your suggestion. This seems an interesting alternative to the replacement of the pinion. By all means, please get in touch by PM and I will analyse this option.
  3. Dear friend, do the following sketches help?
  4. Dear fellow watch enthusiasts, Here we have a senior patient whose only ailment is a broken centre wheel pinion (two of its ten leaves are missing). Please have a look by yourselves. The watch is a 1890s Straight Line 15 Ruby Lever Winder ('Ligne Droite Remontoir Ancre 15 Rubis') with a very large 24 ligne (54 mm) movement. The dial maker's ('Widmer') is the only maker's mark, concealed on the dial's back. My theory is that the damage to the pinion was caused by the sudden release of the barrel. A broken mainspring was lodged inside with unusual thickness and length (0.27 mm, 74 cm) for this barrel size (21 mm), which probably made it subject to too much tension. The replacement mainspring (0.23 mm, 64 cm) that has now been fitted is more suitable according to my calculations. The pallet fork and the impulse jewel were disengaged, but this was easy to correct (the balance wheel was repositioned as shown in the photo), and the going train is now back to working condition except for the centre wheel pinion. I took some additional measurements that could become useful: Centre Wheel outer Ø: 15.52 mm. Centre Wheel inner Ø: 3.33 mm. Centre Wheel arbour length: 12.08 mm. I would ideally like to obtain the spare parts to fit myself. I know some of you will say this is too difficult or too costly or not worthy. However, I also know there must be some connaisseurs out there who will empathise with my urge as a learning collector and watchmaker and hopefully will provide me with some practical guidance. I realise my interest in antique pocket watches may not be shared by a majority of members of this forum. In that case, if there is any other online forum or club that you can recommend then that would also be appreciated. Perhaps you know someone in the area of London who can help. Many thanks in advance for your valuable comments.
  5. Following a string of missteps that costed the integrity of an antique watch, as documented in our forum, and after taking some time to re-consider my future as a horologist, I decided to go back to the 'workshop' with a clear intention to right my wrongs. The subject that lies on my table is an 1890s Swiss ébauche which cannot run its full length and stops after a few hours from winding. Fig. 1. Dial view. Fig. 2. Rear view. The setting was not smooth to start with as the hands were missing some turns of the stem. So I removed the dial to inspect the minute and hour wheels. Fig. 3. Front view with hour and minute wheels visible. With the hour wheel removed, I could notice the action between the minute wheel and the cannon pinion was failing to happen. Fig. 4. Minute wheel-cannon pinion defective action. The culprit has been caught. Fig. 5. Minute wheel with worn teeth. Without the minute wheel, it turns out the watch can run like a century ago. This wheel will have to replaced to re-establish the normal watch operation. I hope you liked this post. Now, my appeal to you, fellow watch enthusiasts. Iif you have a minute wheel 11.2 mm in diameter (diameter for pinion is 3.7 mm) please do get in touch, as that wheel is for this watch.
  6. Alright, so here is my conclusion. At the moment I feel it will be is easier to buy a replacement case with a crown than a replacement crown on its own. So I am marking this case as 'solved'. Thanks to those who contributed their thoughts.
  7. Hey Alaskamick, welcome to this thread! Oh, it could be, but I just checked again and I can guarantee the stem looks complete (unless someone has cut it very neatly). 2425111 Yes, that is exactly the crown! You can see it here too: In this case the bow also matches my model. So where can I get this crown?
  8. I am still stuck with this one, sorry. Any more advice/help anyone, please? For your reference, the case was manufactured by the Elgin Giant Watch Case Co.
  9. Shot for Channel 4 in 1991, The Watchmaker, is a 10 minute documentary which glances at the life of Clifford Norman Bowler (1899-1993) a long-standing English watchmaker and definitely someone many of us would have liked to meet. Mr. Bowler belonged to the precise profession for over 70 years until his death at 93. Initially working for others in Manchester after he left the army, he set up his own repair shop at 54 Mill Lane, West Hamsptead, which he acquired for 100 pounds and run for over 67 years. Today there is a plate commemorating him at the entrance of his former premises. In the film he can be seen at his work bench smoking a pipe or inspecting watches with an eye loupe and at the counter taking several orders from customers (cleaning a pocket watch, changing a strap or a pin). He recounts for the camera his beginnings and how he moved to London, as well as remembering relatives. When asked about the secret of his longevity, he confesses this to owe to a contented mind, regular habits and a peaceful life. Sadly he did not leave any followers: 'All the knowledge that I have obtained and learned during over sixty years that I have been here, it all comes to nothing. I can't pass my knowledge on which I'd like to'. His shop, still vacant more than a decade later after his disappearance, symbolises the emptiness left by an irreplaceable man. There is more info about him in this article: http://westhampsteadlife.com/2014/01/15/a-moment-in-time-on-mill-lane/9921 If you ever met this man or heard about him, your comments could help to honour his memory.
  10. This is the kind of tool I was missing. Stupid me... :pulling-hair-out:
  11. Dear friends, What is the correct method for fitting all pivots in all jewels in a full plate or 3/4 movement like the one below, a Phenix from 1908. Sadly for it, some pivots and jewels were badly damaged as I was unable to align them properly during re-assembly. Although it is too late for this Phenix, your comments may help to prevent a similar 'disaster'. Many thanks.
  12. Stunning work. There you have another ticking fellow who is going to survive us all. Did you use any special tools to create the bow? I precisely need to restore my great grandfather-in-law's silver watch, that has a missing bow, so your comments could come very handy.
  13. Thank you Roger for showing your superb work and wish you success with your growing business.
  14. The staking tool set arrived two weeks later without any unwelcome surprises. If anything, the box was a bit unglued and one of the punches was broken, but this I could expect. I would like to learn more about these tools, so I have opened a new thread with some photos to start a discussion here: http://www.watchrepairtalk.com/topic/3028-one-swiss-staking-set/
