This video details the servicing and restoration of a 25-year-old Omega Dynamic watch, which had never been opened or serviced. The owner experienced issues with the watch failing to start without extensive movement and poor accuracy. The teardown reveals a dry ETA 2892-A2 movement (known as Omega 1108), signs of moisture ingress, and debris on the dial, all indicative of severe lack of maintenance. The video includes a comprehensive cleaning, oiling, and assembly of the movement, highlighting the importance of regular servicing for automatic watches. Additionally, the case and bracelet are sympathetically refinished, and practical tips are provided for polishing and proper spring bar selection. The watch's history and the ETA 2892's reputation as a robust, widely-used caliber in luxury watches are also discussed. Post-service, the watch is accurately tuned and returned to its owner.
Summarizing the Omega Dynamic Service and Restoration:
0:00 Watch Introduction & Issues: An Omega Dynamic, 25 years old and never serviced, is presented. The owner struggles to start it (requiring "star jumps") and reports inaccuracy. The clasp is scratched, and an incorrect spring bar protrudes from the side.
1:07 Diagnosis of Dryness & Contamination: The watch is "dry as a bone," far exceeding the recommended 3-5 year service interval. Signs of moisture ingress, including stains on the Faraday cage and a moist gasket, suggest exposure to humid climates. Debris is also noted on the dial.
1:55 Movement Identification: The watch contains an Omega 1108 caliber, which is identified as an ETA 2892-A2 β a highly regarded, slim, reliable, and accurate movement widely used by numerous luxury brands (e.g., Hublot, Franck Muller, Tudor, IWC, Breitling, Panerai).
4:57 Dial Cleaning & Watch History: After disassembly, observed patches on the dial are successfully removed. The video briefly recounts the Omega Dynamic's history, from its 1968 "flying saucer" design to the 1995 third-generation (the model being serviced), which features a more traditional WWII military-inspired aesthetic.
6:54 Movement Teardown & Root Cause: The disassembly process reveals dried, congealed oil as the primary reason for the watch's poor performance, underscoring the necessity of regular servicing.
9:37 Case & Bracelet Refinishing: The case and bracelet are cleaned and given a sympathetic brushed finish. A key tip is provided: all existing scratches must be removed before applying a new brushed finish to achieve a clean result.
10:28 Polishing Techniques: The presenter demonstrates how to dress a polishing wheel for optimal results and advises against using a brushing wheel for cutting to extend its lifespan.
14:38 Mainspring & Automatic Works Assembly: The mainspring is installed, with an explanation of braking grease for automatic watches, which allows the mainspring to slip when fully wound. The automatic winding mechanism is also assembled and oiled.
17:28 ETA 2892 Praised for Design: The reassembly of the movement highlights the ETA 2892's simple, efficient, and robust design, which contributed to its survival of the quartz crisis and widespread adoption.
20:33 Cannon Pinion Maintenance: The importance of properly greasing the cannon pinion for smooth hand adjustment is emphasized, as dryness can lead to difficulty in setting the time.
23:19 Hacking Lever Functionality: The hacking lever, a simple mechanism that stops the balance wheel during time setting, is demonstrated.
23:47 Final Tune-up & Pressure Test: After assembly, the watch is tuned for accuracy, showing a significant improvement. A new gasket is installed, and the case is pressure tested for water resistance.
26:52 Correct Spring Bar Selection: A clear explanation is given on why the wrong spring bar can protrude from a clasp. Single-flange spring bars are recommended for clasps due to their shorter tips, unlike the double-shouldered ones typically used for lugs.
27:28 Conclusion & Return to Owner: The watch is fully serviced and restored, no longer requiring "jumping jacks" to start. It is returned to its satisfied owner.
