Nixon Sentry Leather Watch. The Sentry Leather is an elegant timepiece with an adventurous side. Think black tie meets block party. The face pops with depth and detail, but with the solid stainless steel case, hardened mineral crystal, and waterproof rating of 100 meter / 10 ATM, you don't have to worry about it not being able to hang in the real world. Taking a classic watch design and adding elements of dimensionality and detail. It’s how Nixon does dressy. Solid stainless steel case, hardened mineral crystal paired with a wide leather strap. A 23mm custom leather band provides sincerely refined style, flexible comfort, and added security with the help of a stainless-steel buckle. Make it your own with multiple dial and band combinations to choose from. Miyota Japanese quartz 3-hand movement with bilingual day and date (English/Spanish). Imported.
