The product

From pocket object to wrist piece.

The Royal Pop is built to be collected, worn, and noticed. Cradle Adapter V1 gives it a new context — the wrist. A precision FKM rubber cradle system that holds the module securely without drilling, gluing, or changing the original piece in any way. Non-permanent. Fully reversible.

Materials & process

Engineered slowly, on purpose.

Cradle Adapter V1 is a single, deliberately small production run. Every cradle is CNC-finished to tight tolerances around the Royal Pop case geometry, paired with FKM rubber and a deployant clasp tuned by hand. Nothing is mass-produced. Nothing is rushed.

Step 01 · Cradle
CNC machined to 40.35mm.
The cradle body is machined from solid stock. The inner socket is measured against the Royal Pop case, leaving a 0.7mm retaining lip that holds the module flush without clamping force.
Tolerance ±0.02mm
Step 02 · Strap
FKM, the dive-watch compound.
FKM (fluoroelastomer) is the rubber used in dive watch straps and aerospace seals. Denser and more UV-stable than standard silicone. Resists sweat, oils, sunscreen. Feels closer to a Rolex Oysterflex than a sports band.
22mm · UV-stable · Skin-safe
Step 03 · Clasp
PW deployant, hand-tuned.
Each butterfly deployant is opened, closed, and adjusted by hand before it ships. The closing action sits flat on the wrist with no spring-bar fumbling and no exposed pin.

Engineering

Precision built
around the Royal Pop.

Every dimension of Cradle Adapter V1 is designed around the Royal Pop modular format. The inner socket, cradle depth, retaining lip, and dual crown clearance notches are engineered to produce a flush, secure, non-permanent fit.
