Caliber
Visual authentication protocol

Trust isn't optional.It's Caliber.

Screen the watch before the deal. Caliber inspects submitted photos and video for model-specific inconsistencies, then gives you a clear evidence record to share.

The protocol

Evidence first.
Confidence second.

A useful screen shows its work. Caliber organizes the visual details that matter before you decide whether to proceed.

01

Dial typography

Character proportions and printing consistency

02

Bezel geometry

Index spacing, alignment, and finishing cues

03

Caseback markings

Reference formatting and engraving structure

04

Visible components

Movement and hardware details when available

Built for the secondary market

Guided capture

A repeatable evidence set from the key watch angles.

Readable findings

Clear flags and gaps instead of an opaque score.

Private by design

Share the record when you choose, not before.

Built to travel

Use Caliber alongside existing collector communities and marketplaces.

What Caliber is not

A certainty machine.

The strongest fakes can fool image-only systems. Caliber makes that limitation explicit, so suspicious or incomplete cases stay visible instead of being waved through.

Straight answers

The fine print matters.

Trust requires clear limits, especially when a decision is being made from photos.
