The Product

Built around the moments that matter on the bench.

Watch movements are unforgiving. A dropped screw can cost hours; a lost crown costs a job. ModMaster was shaped around that reality: a quiet, purposeful surface designed to hold what you set down, exactly where you set it.

Parts Control

Six pockets. Zero guesswork.

Each recessed cup is shaped to hold small hardware securely without creating static cling. Load the first with case screws, the next with spring bars, the third with stems. Your workflow stays organized, visible, and countable.

Precision

A ruler where you'll actually look.

A 30 cm embossed ruler runs along the front edge, within millimetres of the work zone so you can measure a bracelet link, a strap cut, or a case lug without reaching for a caliper.

Every detail earns its place.

01

Anti-static surface

A matte silicone finish that resists dust, repels debris, and won't generate static that clings to hairsprings or balance wheels.

02

Stem channel

A raised rear edge and shallow channel catch rolling stems, pins, and screws before they reach the edge of the desk.

03

Low-profile 3 mm

Thick enough to cushion a movement; thin enough to disappear under a case press or a loupe stand without lifting tools.

04

Heat resistant

Silicone compound rated for contact with hot parts. Safe for soldering jigs, hairdryer-based strap shaping, and crystal work.

05

Non-slip grip

The mat stays where you put it. No sliding mid-operation, no chasing it around the bench when you reach for a tweezer.

06

Easy to clean

Wipe with isopropyl or warm soapy water. Silicone doesn't stain and doesn't absorb oils from movements, lubricants, or hands.

Feels like it was made by someone who's actually dropped a stem on a rug at 2 a.m. The pockets are deep enough to matter, the ruler is right where you need it, and it doesn't slide.

About

Built by someone who's chased a stem across a hardwood floor.

ModMaster started the way most good tools do: out of frustration. After too many nights spent on hands and knees hunting for dropped parts, I set out to design a single, purpose-built work surface that treated small-parts work with the seriousness it deserves. No kitchen silicone. No afterthought branding. Just a mat that makes the bench feel like a workshop again.

We're a small, independent brand shipping one product well before we do anything else. If you see room for improvement, we want to hear it: carsonpirollo@gmail.com.
