·I've just measured the strap - it's definitely 16mm at the clasp.
Strap was FC6167 (18mm tapering to 16mm)
Clasp was FC5012 and that's the Heuer branded version. There is also a Tag Heuer branded version (FC5013).
Of course this is all for the earlier, 36mm re-editions (model numbers beginning CS). The later and larger 39mm re-editions (model numbers beginning CV) would require a wider 20mm strap (and I think 18mm at the buckle) and the model numbers for the buckle would be different.
