Hacking function works great!! stops seconds at 24 hours mark as intended

This vintage watch is in very good overall condition, although it was actively used by a former army member in combat helicopters. The case and bezel are made of stainless steel and show signs of regular use but remain robust, only needing a minor cleaning to regain their shine. The bezel screws on correctly, ensuring good water resistance.

The dial is in perfect condition with hands and inscriptions that are very legible, improving the ease of reading the time. The calendar works impeccably, adding to the daily functionality of the watch. Although the lugs are slightly worn, they securely hold a 20 millimeter wide non-original leather strap that is comfortable and stylish, although it is not the original strap.

The AS 1700/01 automatic movement is notable for its accuracy and durability. It offers an average precision of 0 seconds per day in a horizontal position, -21 seconds per day in a diagonal position, and -14 seconds per day in a vertical position. The amplitude is excellent, varying between 238° and 265° depending on the position, testifying to the good condition of the movement despite its age.

The case back is also in good condition, with clear serial numbers, ensuring the authenticity of the watch. Although the watch functions well, a complete service might be considered due to the unknown service history and the slight advancement of time towards the end of its approximately 41-hour power reserve.

This watch not only has a fascinating history but also robustness and precision that make it ideal for daily use or as a collectible piece. It is sold without warranty, as is often the case with vintage items, and the buyer will be responsible for future service costs.
