The Moonwatch is the most honest chronograph at this price: hand wound, flight qualified history, and a 3861 movement certified by METAS to run between zero and five seconds fast a day while resisting 15,000 gauss. The Hesalite version keeps the original look and costs about €1,100 less than the sapphire model. Against a Tudor Black Bay Chrono or Breitling Navitimer it wears slimmer at the wrist and has a bracelet that tapers from 20mm to 15mm.
It is the chronograph with the strongest real world history, now with Master Chronometer accuracy.

What owners say
On OmegaForums and WatchUSeek owners split between Hesalite for authenticity and sapphire for durability; many report few visible marks after a year and say scratches buff out with Polywatch, while one owner wore through repeated polishing and replaced the crystal. Praise focuses on the bracelet and the 3861. The October 2025 US price rise drew grumbling about value.
