- Dial Design and Origins
- The watch features a silver soleil dial distinguished by the presence of block-shaped hour markers. According to the vendor, this dial configuration reflects design studies developed by the dial maker Singer in the late 1960s. These markers are noted for a mirror-like filling that alters its appearance depending on the angle of light, transitioning between white and dark tones. The design lacks any luminescent material on the indices or the handset. The dial remains free of standard luminescent points, contributing to its distinct visual profile.
- Case and Bracelet Specifications
- The watch is housed in a 36mm stainless steel Oyster case. It is completed by a fluted bezel, which the source identifies as white gold. The exterior condition is described as sharp, retaining the factory-intended case proportions and crispness of the bezel edges. The timepiece is mounted on a folded Jubilee bracelet, referenced as 6251H. The bracelet assembly includes end links stamped with the number 55. The clasp features a date stamp of 4 68, providing a chronological link to the production era of the watch.
- Mechanical Details and Maintenance
- The movement is identified as a slow-setting self-winding caliber. The vendor reports that this mechanism has been fully serviced by their watchmaker to ensure operational readiness. The service history is confirmed by the vendor, and the movement is currently functioning as intended for the Oyster Perpetual system.
