Dark Blue Circular Pattern Rotor: Modern NH34 & NH36 Movement Upgrade

Give your Seiko NH34, NH35, NH36, or NH38 build the modern visual heartbeat it deserves with this dark-blue circular-pattern rotor. The medium-tint azure looks sharp behind both a sterile white dial and a stealth-black one, adding a clean pop of color without overpowering the overall theme. Its ever-spinning surface catches daylight in soft waves, turning what is usually hidden into the first thing admirers notice when the case back flips open.

Precision meets personality here. CNC-milled from aircraft-grade stainless steel and then treated with scratch-resistant anodizing, the disc weighs exactly 2.2 g—Seiko spec—so amplitude stays within factory tolerances while winding efficiency actually increases. Eight countersunk perforations zero the static balance, delivering the same silky bidirectional sweep you expect from stock, yet now dressed in minimalist, modern lines.

Installation is a literal ten-second affair: drop it over the stock collar, tighten the single screw, probe knife away, and you’re chasing Instagram hearts before your next sip of coffee. No re-indexing, no movement removal. Makers of both vintage-styled field watches and ultra-clean Bauhaus timepieces report that the deep navy disk becomes an extension of their dial palette, marrying modern simplicity with historical mechanics in one glance.

Stock is limited to this single production run of 350 pieces. Each rotor arrives sealed in anti-static foam along with a pair of micro-screwdrivers—so you can perform the upgrade at your desk and be back in wrist rotation the same day. Tap “Add to Cart” if you want your NH to hum, glow, and turn heads for less than the price of a nato strap.
