Physical verification
- Photograph the front, case back, space between the lugs, clasp and bracelet reference markings separately.
- Match the dial, hands, tachymeter bezel and crystal to the same reference.
- Record the warranty card, Master Chronometer certificate and box components individually rather than describing the watch simply as 'boxed'.
