Design Differences
Movement
Both use the manual-wind Caliber 1861 
(or 3861 in newer Moonwatches).
The FOIS originally came with the 1861, 
while modern Moonwatches now have the 
3861 (anti-magnetic, Co-Axial 
escapement).
Which One to Choose?
 Moonwatch if you want:
The NASA-certifi ed Moon landing heritage.
Classic hesalite crystal (authentic to vintage models).
Updated 3861 movement (in newer versions).
FOIS if you prefer:
A cleaner, vintage-inspired look (symmetrical case, 
alpha hands).
Pre-Moon history (first Omega in space).
Sapphire crystal (more scratch-resistant).
