NH Movement Bridge - Côtes de Genève - Circular - Silver

The Côtes de Genève motif is the best known of all the decorations adorning watch movements. Perhaps this is due to its name that initially seems both striking and somewhat strange, or possibly because it is so strongly present on movements. Whatever the case, this pattern traced on the smooth surfaces of mechanical (and indeed quartz) movements is a familiar sight on the watchmaking scene - to the point where one almost forgets that finishes are not a purely aesthetic element.

Here is a decorated NH movement bridge, Côtes de Genève in a Circular design.

With a sapphire caseback, it is all the reason to beautify the movement and improving the aesthetic.

[Installation Guide]
  1. Tools required: (i) 2-3mm flat screwdriver, (ii) 1.0-1.4mm flat screwdriver and (iii) tweezer.
  2. Remove existing rotor with a 2-3mm flat screwdriver.
  3. Unscrew and remove the two automatic train bridge screws on the NH movement bridge with a 1.0-1.4mm flat screwdriver (labelled in red 1 & 2 as show in the photo).
  4. Remove the automatic train bridge with a tweezer (circled in green as show in the photo).
  5. Replace with decorated bridge. Affixed by gently screwing and tighten the two blue screws in place.
  6. Lastly, position and screw down the rotor.

Note: Removable and placement of automatic train bridge have to be done carefully with a steady hand to avoid misaligning the pawl lever (aka magic lever) and popping out the second reduction wheel (the wheel the magic lever clutches onto). The automatic train bridge screws are 1mm in size! Therefore, please ensure you take great care when working with these screws and avoid losing them. Due to difficulty working with a movement bridge, it is ONLY recommended for professional watchmakers and highly skilled/experienced modders with great level of finesse.

Absolutely worth it!

These are what exhibition casebacks are made for! The blue screws are a nice touch.

Best way to upgrade the look of your NH--

If you're gonna have an open caseback might as well make it look super spiffy. This, on top of a custom rotor, was the best decision I've made. It does nothing in terms of performance but it really glistens when you tilt the watch in a circular motion.

Absolutely beautiful!

This bridge brings the bling to your bland NH movement. If you plan to use a display case back you should definitely consider getting one of these custom bridges with the heat blued screws. If you’re going to show off the movement, do it right. 😉 And to put it over the top, consider one of their custom rotors. All great quality in my experience.

Just that little bit extra.

Lets face it, stock Seiko NH movements are a bit boring visually. They are a workhorse, but a rather plain workhorse. This bridge is a way to give them some fancy clothes and make that sapphire caseback worth installing. I'll also mention that I asked and LA accepted my request to install the bridge on the movement I bought along with the bridge prior to shipping it. Five starts for the part, and another five stars for the extra service.


This bridge will definitely make your NH movement look amazing. Just be careful with those tiny screws. I was terrified I might sneeze and lose them forever. 😂

Amazing look the blue screws could be bigger
