Authentication

Every watch that reaches this catalogue has been through our bench first. Here is what that actually involves.

Reference and serial verification

Reference and serial numbers are read from the watch itself — between the lugs, on the rehaut, or on the caseback as the model dictates — and checked against factory records for the production period, the dial and bracelet combination, and the correct case dimensions.

Case, bracelet and dial

We examine the case for polishing, lug shape and the crispness of the chamfers, since over-polishing is one of the most common ways value is quietly lost. Bracelet stretch is measured, clasp codes are checked against the case, and the dial and hands are inspected under magnification for correct printing, lume type and any refinishing.

Movement

The caseback comes off. Our watchmakers confirm the calibre matches the reference, look for non-factory parts and previous service marks, and run the watch on a timing machine across multiple positions. Amplitude and beat error are recorded.

Water resistance and function

Where a model is rated for it, pressure testing is carried out after any gasket work. Chronographs, date changes, GMT hands and rotating bezels are all cycled and checked.

What goes in the listing

Whatever we find. If a watch has been polished, if the bracelet has stretch, if the box or papers are absent, or if a part has been replaced at service, it is written into the description. A listing that says nothing about condition is a listing that is hiding something, and that is not how we sell.

If you disagree with us

Have any watch you buy from us independently verified by a watchmaker of your choosing. If it is not as we described it, send it back — see our returns policy.
