The Cyma Tavannes 504 watch movement, likely designed by Record around 1970 and also applied by Longines, features a manual wind function, sweep second, adjustable stud holder, KIF shock protection, and sweep seconds. Its unique design places the minute wheel and pinion under the balance, allowing for a relatively large balance. Limited data and documentation are available for this movement line, with only Boley and Flume providing partial information. The movement shares the same staffs and stems with Longines, according to Boley's specifications. This movement is not commonly found in older movement registers.
