That's the one - my mistake. Thanks for the help Stewart & email sent. Tom

: Hi Tom,
: If it's an 11630, it's not a 'Viceroy', they were an 1163.

: I presume you have this model:

: If it is a 11630 Black dial, white subs with red highlights, then
: it's less common than a Viceroy.
: It should have a flat mineral glass, the crystals are available
: from Cousins (31mm x 3mm I think). The lume dot was just filled
: with lume, not a 'pearl dot' like Rolexs have.

: I presume you are in the UK, if so, let me know if I'm correct
: about the above info, I know a UK guy that can fit a new crystal
: & relume the bezel dot (matching the lume patina on the
: hands) for a very reasonable rate.
