39mm EXP 24 Hour GMT Watch Case Fixed Bezel  Sapphire for NH35/NH36 Movement Frosted Steel Strip

Core Specifications & Highlights

• Model Style: Explorer / OP-style with a fixed 24-hour GMT bezel (marked on the case, not a rotating bezel).

• Compatibility: Designed for NH34 / NH35 / NH36 movements.

  • *(Note: The title says NH35/NH36, but a 24-hour GMT hand requires an NH34 GMT movement. The case likely supports the taller NH34.)*

• Key Upgrade: Sapphire Crystal with an optional date magnifier (cyclop).

• Case: 316L stainless steel, 39mm diameter (without crown), 12mm thick.

• Water Resistance: 10ATM (100 meters) thanks to the screw-down crown and case back.

• Dial Fit: Accepts standard 28.5mm - 29.3mm dials.

• Strap/Bracelet: Comes with a 20mm lug width bracelet (frosted steel strip style included in the set).

Full Package Contents (Set Included):

You receive everything needed to build a complete watch head:

1. Case (with fixed bezel and sapphire crystal installed)

2. Bracelet (Frosted steel strip)

3. Screw-down crown

4. Waterproof gaskets

5. Choice of back cover (solid or glass exhibition see-through)

6. 2 spring bars (for attaching the bracelet)

Important Notes for Builders/Modders:

1. Movement Selection: To use the 24-hour GMT function, you must install an NH34 movement. The NH35/NH36 will not drive the independent GMT hand.

2. Dial & Hands: This set does not include a dial or hands. You will need:

   • A 28.5mm-29.3mm dial.

   • A set of hands compatible with the NH series movement (NH34 for GMT).

3. Bezel Function: The fixed bezel means the 24-hour scale is stationary. To track a second time zone, you would set the 24-hour GMT hand to your reference time (e.g., home time) and then read the hour in the second time zone from the bezel scale relative to the GMT hand.

This is a popular and high-spec base for creating a custom "Explorer II" style GMT watch. The sapphire crystal and 10ATM water resistance make it a robust and premium choice.
