TAG Heuer Calibre 5
ProbableWorth being precise about because the designation is a marketing label rather than a caliber identity: Calibre 5 has covered more than one outside base over its life, so it does not by itself tell an examiner what is inside the watch. The Isograph carbon-composite hairspring is a specific and checkable execution within it, and TAG Heuer's claims about it were revised after launch — which is recorded here as a reason to read the reference rather than the label.

Open questions
Which references carried which Calibre 5 base
Which outside movement bases has TAG Heuer sold under the Calibre 5 designation, and which reference carries which?
Scope Consequential because the designation is a label rather than a caliber identity. Without a mapping an examiner cannot state what should be inside a Calibre 5 watch, which means the movement — normally the most informative part — establishes very little on these references.
