Watch Movement Cushion and Bench Mat Guide: Pad Sizes and Surface Protection
Select the correct watch movement cushion, casing gel pad, or Horotec bench mat by diameter and thickness. Compare rubber pad sizes from 20mm to 75mm and submit measurements.
Watch movement cushions: protecting calibers and crystals during bench work
A compliant resting foundation is essential on any watchmaker bench. During uncasing, hand lifting, regulating, battery replacement, or screw tightening, a watch requires firm support. Resting an uncased caliber or polished case on a hard surface scratches bezels, chips crystals, and transmits shock into delicate wheel arbors and balance staffs.
Movement cushions, gel pads, and flexible mats form a vital barrier. They absorb downward force, dampen vibration, and prevent spinning during tasks like stuck watch case back removal. However, an undersized cushion allows baseplates to rock under pressure, while a pad without center clearance can crush the cannon pinion. Matching pad diameters and center apertures ensures safe assembly.
Graduated rubber movement cushions: six sizes from 20 mm to 43 mm
For direct support of uncased movements, the Kocandy catalog offers a graduated set of white rubber movement cushions. Designed to shield baseplates from bench wear, this set supplies six circular pads: 20 mm (0.79 in), 25 mm (0.98 in), 30 mm (1.18 in), 32 mm (1.26 in), 35 mm (1.38 in), and 43 mm (1.69 in).
Each cushion features a uniform height of 12 mm (approximately 0.5 inches) and a 5 mm center through-hole. The complete six-pad set has a catalog weight of 95 grams. Molded from dense white rubber, the cushions provide wear resistance and elasticity to protect movement bridges without transferring bench grit.

Center hole clearance and diameter matching for uncased calibers
Matching a caliber baseplate to a cushion requires checking perimeter support and central clearance. An uncased mainplate must rest level. If the cushion is narrower than the movement, driving screws causes the plate to tilt, risking bent pivots or cracked jewel settings.
The 5 mm center relief hole is equally critical. When placing a movement dial-side down, protruding cannon pinions, hour wheel pipes, and center arbors must remain suspended. Resting on a solid pad without center relief drives the center pinion upward into the jewel setting.
To select the correct size, measure the baseplate diameter with a caliper. Choose the pad whose diameter matches or slightly exceeds the plate boundary so the rim is supported while central arbors clear the 5 mm opening.
PU crystal protection cushion with chrome-plated metal ring
When servicing cased watches, changing batteries, or opening case backs, the timepiece rests face down with its crystal bearing downward force. Placing a domed crystal on a hard surface risks cracking glass, scratching anti-reflective coatings, or marring bezels.
To protect crystals, the Kocandy catalog features a polyurethane (PU) cushion encased in a chrome-plated metal retaining ring. The soft PU face cushions crystals without scratching, while the chrome ring preserves geometry under load. An anti-slip rubber base anchors the cushion during case opening.
A catalog detail should be noted: while the title and slug reference a 50 mm designation, the specification table records dimensions as ⌀70 mm x 13 mm. In bench practice, this 70 mm diameter supports standard and oversized watches. An auxiliary insert disc helps center smaller cases.

Large 75 mm casing gel cushion for oversized watches and metal objects
Modern wristwatches frequently exceed 42 mm in diameter, with sports chronographs extending past 45 mm. Supporting these wide cases requires an expansive, compliant base. For larger watches, the Kocandy catalog provides a 75 mm watch casing gel cushion.
Catalogued with a diameter of 7.5 cm (75 mm), height of 2 (approx. 20 mm), and weight of 125 grams, this white cushion features a soft plastic gel surface. The compliant gel contours under bezels and crowns, absorbing shocks and shielding polished cases from scratches.
The underside features a non-slip material that prevents sliding. The catalog states this tool serves watch casing tasks as well as repairing delicate metal objects and glass items. Its wide 75 mm profile provides exceptional stability when driving case screws.

Horotec MSA 24.213.214 green bench mat: chemical resistance and dimensions
Beyond individual pads, a watchmaker workstation requires a protective bench mat. A bench mat shields tools from hard tables, provides visual contrast against tiny parts, and stops dropped screws from bouncing. In the Kocandy catalog, this foundation is fulfilled by the Horotec MSA 24.213.214 repair bench mat.
Supplied as a single green mat, the unit measures 32 cm by 24 cm (approx. 13 by 9.45 inches) with a 2.0 mm thickness and a weight of 170 grams. Molded from soft elastomer, its anti-skid surface deadens the fall of dropped screws or springs.
Chemical resilience is a key feature: the catalog states the mat withstands bench solvents like benzine, alcohol, and fluids used alongside watch cleaning and polishing supplies. However, the catalog notes an explicit exception: the mat does not withstand acetone. Contact with acetone softens the elastomer, so acetone must remain restricted to glass jars.

Cushion and mat specifications: comparative catalog dimensions
Selecting the appropriate cushion or bench mat depends on whether you are supporting an uncased caliber, protecting an exterior watch crystal, or outfitting an entire work surface. Reviewing catalog materials, dimensions, and heights ensures each fixture matches your bench requirements.
The table below compares the four surface protection products from the Kocandy catalog, detailing stated materials, physical dimensions, weights, and primary workshop roles.

Matching cushions to workshop operations: uncasing, hand setting, and case closing
Different repair stages exert distinct forces on watches. Caliber work demands rigid, level support with center arbor clearance, while closing cases requires broad compliance to cushion crystal tension. When pressing crystals or snap case backs, pairing compliant cushions with properly sized watch case press dies prevents uneven pressure. Similarly, inspecting and renewing worn seals with matching watch case back gasket O-rings before closing ensures moisture resistance.
The operational guide below maps common bench procedures to recommended catalog cushions and craft precautions.
Workshop operation | Recommended support | Supporting mechanism | Craft precaution |
|---|---|---|---|
Caliber disassembly and bridge screw removal | 6-Piece Rubber Pad Set (20–43 mm) | High-density rubber holds plate flat while 5 mm center hole clears center pinions | Choose pad diameter equal to baseplate; avoid resting on balance wheel or pallet bridge |
Hand setting and dial installation | 6-Piece Rubber Pad Set (matched size) | Resilient rubber absorbs vertical hand presser force without plate flex | Verify dial markers do not contact hard bench edge; keep center hole aligned |
Battery replacement on quartz cases | PU Crystal Cushion (⌀70 mm) | Soft PU foam cradles crystal while chrome ring resists radial distortion | Place watch face down; verify crown and pushers clear the metal perimeter ring |
High-torque case back removal or closing | 75 mm Casing Gel Cushion | Gel material distributes torque across bezel; non-slip base prevents spinning | Inspect gel surface for metal filings before placing polished bezels face down |
Component cleaning and small-part assembly | Horotec MSA 24.213.214 Bench Mat | 2.0 mm anti-skid surface cushions falling screws; resists alcohol and benzine | Never expose mat to acetone; wipe spills immediately to maintain surface elasticity |
Bench discipline: cleaning, solvent exposure, and pad maintenance
Even a properly chosen cushion can damage a fine watch if cleanliness is neglected. The soft surfaces of rubber pads, PU cushions, and casing gels attract airborne dust, metal burrs, and brass chips. If a polished crystal or bezel is pressed against embedded grit, the trapped filings will score the finish.
Inspect cushions under magnification before placing components on them. Rubber pads can be washed with water and dried, or dabbed clean with dry putty. Store cushions under dust covers when idle. Furthermore, observe chemical limits strictly: while the Horotec mat resists benzine and alcohol, never expose PU, gel, or bench mats to acetone.
