Technical principles

Repair standards for watches that deserve restraint

This page explains how we think about repair decisions, especially when a watch is valuable, sentimental, vintage or difficult to replace.

Movement diagnostics

Timing, amplitude, beat error, winding feel and power-reserve behaviour help reveal what the owner cannot see. A watch that loses time may need demagnetising, regulation, lubrication, parts replacement or a full movement service depending on the evidence.

Cleaning and lubrication

Where a complete service is approved, the movement is handled according to its condition and architecture. Old lubricant, dirt and wear particles can shorten the life of pivots and jewels. Correct lubrication is measured work, not a cosmetic upgrade.

Sapphire crystal handling

Sapphire is hard but not invincible. A chipped edge can compromise seals, and damaged anti-reflective coating can make a watch look older than it is. We assess fit, gasket contact, cyclops alignment and water-resistance implications before recommending replacement.

Case and bracelet preservation

Many owners want a watch to look fresh; many collectors want the original lines preserved. We ask which goal matters more. Inspection lighting helps reveal brushing direction, rounded edges, deep scratches and previous polishing patterns.

Vintage repair principles

Vintage repair is not modern refurbishment. Dial patina, aged lume, period-correct crowns and worn bezels may be part of the watch’s identity. We will not recommend aggressive restoration simply because it creates a brighter before-and-after image.

Documentation after repair

After eligible work, clients receive practical service notes: what was addressed, what remains a future concern, how to wind or store the watch, whether water resistance was tested and when a follow-up service is recommended.

Brands and watch types we commonly discuss

Examples are descriptive only. We are independent and not affiliated with these manufacturers.

Divers and sports watches

Water-resistance, bezel action, crown tube wear, bracelet stretch and impact history are common concerns for sports watches.

Dress watches

Thin cases, precious-metal surfaces, hand-wound calibres and vintage dials require careful handling and conservative polishing choices.

Chronographs

Chronograph systems require precise testing of start, stop, reset, pusher feel and amplitude changes under load.

Quartz watches

Battery leakage, coil damage, moisture and crown issues are assessed before assuming a simple battery change is enough.

Integrated bracelets

Bracelet geometry, clasp parts and refinishing transitions can be complex and should be documented before restoration.

Heirloom watches

Sentimental value changes the repair decision. Sometimes the right repair is the most stable, reversible and respectful one.
