What watchmakers are saying, and what you want to know.

The silicone compound we use is formulated with a matte, low-surface-energy finish that measurably reduces static cling compared to standard glossy silicone. Hairsprings and small parts don't stick to it the way they do to a typical kitchen-style mat. It's not an ESD workstation (that would require a grounded conductive surface), but for watch work, it's the right balance of cost and performance.

No. The ruler is embossed directly into the silicone. It's part of the mat's geometry, not printed or painted. Same for the ModMaster wordmark in the corner, which is also embossed. Nothing to fade, rub off, or peel.

Wipe with isopropyl alcohol for oils and lubricants, or warm soapy water for general cleaning. It's also dishwasher-safe on the top rack if you want a deep clean. Silicone doesn't absorb liquids or odors, so the mat should stay fresh indefinitely.

The pockets are 3 mm deep and 24 mm across, sized specifically to cradle crowns, stems, and small screws without them rolling out. The silicone's grip also helps. You can turn the mat nearly vertical and the parts won't fall out.

Yes, rated up to 230 °C / 446 °F. You can set warm crystals, hairdryer-shaped straps, and soldering jigs on it without marring. We don't recommend direct contact with open flame or a live soldering iron tip, but for typical watchmaking heat work, it's well within range.

No. The non-slip silicone grips most surfaces including glass, wood, metal, and laminate. Even during operations that involve downward pressure (case presses, crystal lifts), the mat stays put.

It was designed for watchmaking, which is why the pockets, ruler, and edge channel exist. But the same features work beautifully for modding, small electronics, jewelry repair, and general hobby work. If you deal with small parts, the mat earns its place.

ModMaster ships via Amazon FBA, which means Amazon Prime two-day delivery in most regions and full Amazon return protection. Orders placed before Amazon's cutoff typically arrive within 2 business days.

ModMaster carries a one-year limited warranty against manufacturing defects, handled through Amazon. If the silicone tears, delaminates, or arrives damaged, open a claim from your Amazon order page and Amazon will process the replacement or refund under their A-to-z Guarantee. All warranty, return, and replacement requests are managed through Amazon.

We're launching with one mat (the 450 × 300 mm watchmaker green) because we wanted to get it right before expanding. Larger sizes and a charcoal colorway are on the roadmap for later in 2026.
