Automatic Movement

A self-winding movement: a rotor converts wrist motion into mainspring tension.

Movements & Calibers

Balance Wheel

The oscillator: a weighted wheel and hairspring that set the watch's rate.

Movements & Calibers

Escapement

The escapement meters energy and gives the balance its impulse.

Movements & Calibers

Manual Wind Movement

Hand-wound: crown, ratchet wheel and click convert turning into stored torque.

Movements & Calibers

Dumont Tweezers

The standard horological tweezer: numbered by tip shape and strength.

Hand Tools & Tweezers

Screwdriver Set

Blades sized to the slot: the difference between a screw and a ruined screw.

Hand Tools & Tweezers

Loupe

The standard 2.5× to 10× eye loupe — the first tool worth buying properly.

Hand Tools & Tweezers

Mainspring Barrel

The power source: a coiled spring in a toothed drum, released in a controlled way.

Movements & Calibers

Watch Oil

Low-viscosity synthetic oil for bearings — applied in very small quantities.

Lubricants & Cleaning

Case Opener

A tool for removing screw-down and friction-fit case backs without marking them.

Hand Tools & Tweezers

Timegrapher

Measures rate, amplitude and beat error — the instrument that makes regulation possible.

Testing & Regulation

Quartz Movement

A crystal oscillator, a divider chain and a stepper motor instead of a balance.

Movements & Calibers

Stainless Steel Case

The housing: seals the movement, carries the lugs, sets the water resistance.

Cases, Dials & Hands

Ultrasonic Cleaner

Cavitation in solvent removes oil and debris from parts you cannot reach.

Lubricants & Cleaning

Sapphire Crystal

Synthetic sapphire glazing: hard, scratch resistant, and brittle under point load.

Cases, Dials & Hands

Dial

The face: substrate, finish, indices and the feet that locate it on the movement.

Cases, Dials & Hands

Hands Set

Hour, minute and seconds hands, fitted with a press and checked for clearance.

Cases, Dials & Hands

Grease

High-viscosity lubricant for the barrel, gaskets and slow heavily loaded parts.

Lubricants & Cleaning

Cleaning Solution

Solvent and rinse fluids that remove old oil without attacking the metal.

Lubricants & Cleaning

Case Press

Closes friction-fit backs and crystals with even, controlled pressure.

Hand Tools & Tweezers

Pin Punch Set

Parallel punches for driving out pins, removing links and freeing stuck arbors.

Hand Tools & Tweezers

Crown

The control: winds the movement and sets the hands, through a sealed tube.

Cases, Dials & Hands

Gaskets

Elastomer seals at the back, crystal and crown — what water resistance actually is.

Cases, Dials & Hands

Cleaning Basket

A mesh basket that holds small parts through wash, rinse and dry cycles.

Lubricants & Cleaning

Water Resistance Tester

Applies pressure or vacuum to prove a sealed case still seals.

Testing & Regulation

Demagnetizer

Removes residual magnetism — the cheapest fix for a watch that suddenly runs fast.

Testing & Regulation

Bench Magnifier

A stand-mounted lens with illumination for inspection and long sessions.

Testing & Regulation

Regulating Tool

Adjusts rate: an index regulator, or timing screws on a free-sprung balance.
