Hesalite vs Sapphire Crystal: Which to Choose?
One of the key decisions when purchasing a Moonwatch is choosing between the Hesalite and sapphire crystal versions. According to Omega, the Hesalite crystal is historically accurate, as it was the material used on the original Moonwatches. Hesalite is shatter-resistant and provides a warmer, more vintage aesthetic. The sapphire crystal offers superior scratch resistance and allows for a display caseback to view the Calibre 3861 movement.
