Glycine Combat Sub 39 vs Glycine Combat

Both are automatic Glycine divers on the same GL224 movement, so the real choice is size and bezel. The Combat Sub 39 is the better watch for most wrists: 39mm wide, 11.2mm thick, 300m water resistance and a flat sapphire crystal that sits low under a cuff. The 41mm Combat is the larger, more casual option with a ceramic bezel and a box sapphire crystal, but it is rated to 200m and wears noticeably thicker. Owners of the 39 consistently praise how it disappears on the wrist; the 41 draws mixed comments on bulk for smaller wrists.

• Choose the Combat Sub 39 if you want a compact, thin diver rated to 300m that slips under a shirt cuff and suits wrists under about 7 inches.
• Choose the Combat if you prefer a larger 41mm case, a scratch-resistant ceramic bezel and a box sapphire crystal with vintage character.
