这是英文资料的原文，供参考：Omega wanted an automatic chronograph and turned to F. Piguet to develop it. The result was the ebauche Cal. 1285 and Cal. 1286, a much-modified version of Cal. 1185/1186. They share many similarities but also have key differences: Thi**ovement runs at 28,800 A/h, is larger and thicker, and some include a Co-Axial escapement for Omega. The subdials are also modified: All feature a 30 minute counter at 3:00, but the Omega ebauches have a 12 hour counter at 6:00, where the seconds are found on other movements in the family.
