Glycine Airman Vintage The Chief Purist vs Glycine Airman Purist Men's Watch GL0494

Both are Swiss-made Glycine Airman Purist watches with the same SW330-2 automatic movement, a 24-hour dial and a bi-directional rotating 24-hour bezel, so they track a second time zone the same way. The Chief Purist is the smaller, dressier one: 40mm case, box sapphire, brown leather strap, but only 30m water resistance and a push-pull crown. The Airman Purist GL0494 is the tougher daily wearer: 42mm, screw-down crown, 100m water resistance and a nylon strap. Buy the 40mm Chief for a slimmer wrist or office wear; buy the 42mm GL0494 if you want a watch you can swim and travel with.

• Choose the Chief Purist if you want a smaller 40mm case, a blue dial and a leather strap for dressier wear.
• Choose the Airman Purist GL0494 if you want 100m water resistance, a screw-down crown and a nylon strap for daily and travel use.
