Petrichor 37mm Case – Rose Gold

The Rose Gold Petrichor brings warmth to our original case design. The same 37 mm platform with its vintage-inspired curves, domed sapphire crystal, and low-profile silhouette — finished in rose gold PVD over 316L stainless steel. The rose gold tone shifts between pink and copper depending on the lighting, giving the case more visual depth than a single flat color. This is a Nomods original design, not a homage to any existing watch. Built for NH35 and NH36 movements with a 28.5 mm dial opening, ready for your custom build.

Specifications

Compatibility

Movements: NH35 and NH36. The Petrichor is designed exclusively for these two movements. The NH72 skeleton movement also fits, sharing the same physical dimensions. If you want a skeleton build in rose gold, pair this case with an NH72 and a 28.5 mm skeleton dial.

Dials: 28.5 mm. Rose gold pairs well with warm-toned dials — chocolate, champagne, or rose gold skeleton dials for a monochromatic look. Darker dials like black or dark blue create stronger contrast.

Hands: Any NH-series compatible hands (hour 1.50 mm, minute 0.88 mm, seconds 0.20 mm). Rose gold hands will match the case; silver hands create a two-tone effect.

What’s Included

• Petrichor case body (316L stainless steel, rose gold PVD finish)
• Domed sapphire crystal (pre-installed)
• Crown (screw-down)
• Gaskets

Tools are not included. You will need a case opener, hand press, stem cutter, and movement holder for assembly.

Designed by Nomods

The Petrichor is an original Nomods design, and the rose gold version highlights what makes it different from cases in the modding market. Where most PVD-finished cases use angular, modern shapes, the Petrichor’s flowing 1960s-inspired contours give the rose gold coating more surface area to play with light. The curves catch and release light gradually rather than in sharp facets, which makes the rose gold read as richer and more nuanced than it would on a flat-sided case. The domed sapphire crystal follows this same philosophy — a curved surface that keeps the profile low while adding visual depth from every angle. Each case is checked for PVD consistency and finishing quality before shipping.

Build Guide

Difficulty: Easy to Moderate — drop-in for NH35 builds. Same assembly process as the Silver Petrichor.

Tools needed: Case opener, hand press, stem cutter, movement holder.

PVD care note: When using a case opener on the rose gold Petrichor, wrap the contact points with tape or use a soft-jaw opener to avoid scratching the PVD finish. PVD is durable for daily wear but can be marked by metal tools during assembly.

Common mistakes to avoid:

• Stem cutting: Measure twice before cutting. Match the stem length precisely to the crown tube depth.
• Crown seating: Ensure the crown screws down fully against the gasket for proper water resistance.
• Dial alignment: Seat the dial feet firmly before lowering the movement into the case.
