Explore our process

Before it becomes yours.

Every watch has a history. Our work is to look closely, understand the piece, and help you make an informed choice.

Experienced luxury watch professionals assess authenticity through movement inspection, identifying-detail checks, component examination, and mechanical performance testing.

A watch’s identity.

We review the reference, serial, and identifying details for consistency with the watch being described. The movement is examined in relation to its brand, model, and production period.

These details help us assess the individual watch, rather than rely on its appearance alone.

Every component matters.

The dial, hands, bezel, crown, bracelet, and clasp are examined as part of our assessment. Originality, genuine replacement parts, and disclosed custom features are considered individually.

A genuine replacement component and a part original to the watch describe different histories. Our team can explain the information available for the piece you are considering.

Performance, assessed.

Timekeeping and mechanical operation form part of our inspection. Pre-owned watches are tested and serviced when necessary.

Authentication, inspection, and servicing describe different work. Service history, work performed, and inspection dates are specific to the watch; available information is described in the listing or confirmed by our team.

Ask for the available service details of your chosen watch.
