  1. I have been fixing a Grosvenor pocket watch with a Pierce 160/22 movement recently. I have been trying to repair the balance as the original had a broken hairspring and a broken pivot. Are there any modern versions of the balance or anywhere I may be able to get an original as I have had little success trying to fix it.
  2. Thank you. I am fairly sure that is right. It looks almost identical and is the right size. I will try and get parts based on that.
  3. The only markings on the movement are the words Swiss Made, 15 Jewels and a small 5 under the balance arm. I don't currently have a very accurate caliper but I think it is 34.7mm rather than 36.4 as the Unitas 6497 movement wouldn't fit. Here is a picture of the dial side but I haven't seen any writing on it. I do not believe that the movement has ever been changed since it was made in around the 1930s.
  4. Thank you but I should have mentioned before, tried a Unitas 6497 clone movement to see if it was the correct size. The gears are far finer and the escape wheel teeth are the wrong size and it was slightly too short. It has a Swiss Lever escapement as far as I can tell and is about 4.5mm in height. If it helps the mainspring barrel is the size of the winding gear on the top and seems to be fully attached to it.
  5. Hello, I have been trying to repair an old Grosvenor pocket watch for a while and have discovered that the escape wheel pivots have snapped. I don't have the equipment to replace the pivot on the existing parts (no lathe) and have been trying to source a new escape wheel. I am in the process of finding a new balance staff. Does anyone have any idea what the movement is or where I could find the dimensions of spare balance wheels to replace it? The movement is approximately 35mm in diameter. I apologise for my bad photography.
  6. I have been interested in mechanical watches for several years and have always wanted to know things work, probably to a fault. I have only recently become interested in repairing watches and clocks after first fixing a pendulum clock (learning to be very careful with mainsprings) and then trying to repair an old pocket watch (learning to always be careful with hairsprings and escape wheels). With only limited equipment and time, I try to find the simplest ways of solving problems with the fewest possible tools.
