MASTER MOD - BLACK

The Master Mod Black is a full-black sport Seiko mod built around a 40 mm stainless steel case with a bidirectional bezel — the kind of watch that reads serious without being heavy. The black dial, black bezel, and NH35 movement make it a no-nonsense daily driver: understated enough to wear anywhere, with enough tool-watch DNA to satisfy enthusiasts who know what they are looking at. The choice between steel bracelet and rubber strap lets you tune it toward dressy or active, and the solid steel case back keeps the profile clean.

Features

• 40 mm stainless steel case – a well-balanced size that sits confidently on most wrists without overreaching; clean lug lines
• Automatic Seiko NH35 movement – hacking seconds, hand-winding, approximately 41 hours power reserve at 21,600 bph; the dependable backbone of this build
• Sapphire crystal with anti-reflective and scratch-resistant coating – high-clarity glass that keeps the black dial visible and glare-free across lighting conditions
• Super-LumiNova – applied to hands and indices for reliable legibility in darkness; a practical necessity on any serious tool-watch mod
• Screw-down crown & 5 ATM water resistance – securely threaded crown, rated for daily water exposure; suitable for rain, sport, and hand-washing without concern
• Bidirectional bezel – rotates both ways, useful for elapsed time tracking across multiple time references
• Adjustable bracelet: stainless steel or rubber, with safety folding clasp – two strap personalities from one watch; steel for the office, rubber for the gym or outdoors
• Solid stainless steel case back – closed back for a cleaner silhouette and a more traditional tool-watch finish

Built to Wear, Not Display

This is a handcrafted Seiko mod made for people who want a reliable automatic watch they can actually use every day — not a conversation piece that lives in a box. Hand-assembled by MedoMods in Germany, shipped EU-wide without customs charges. The NH35 keeps running whether you notice it or not. That is the point.
