Speedmaster: Hesalite vs sapphire
The modern Moonwatch comes in Hesalite and sapphire variants. Same story, different crystal and caseback. Mixing comps creates fake deals.
Hesalite for heritage
Hesalite is closer to the NASA-qualified look. It scratches more easily than sapphire. Many owners accept light marks as part of the tool-watch character.
Sapphire for the movement
Sapphire adds scratch resistance and usually a display caseback so you can see the 3861. It often trades at a modest premium to Hesalite.
How to buy
Open each reference separately, toggle Canada all-in, and prefer Authenticity Guarantee or trusted dealers. Rank by trust after the crystal is confirmed.
