Rare Smiths spotted

On page 15 of Issue 46 of QP Magazine, in an article about the watches worn by visitors to last November's SalonQP, there's a picture of the jeweller and BHI member, John Clark. He's wearing a Smiths Everest. And not just any Smiths Everest. There are two hints:
 - too many jewels: you can just make out that there are 25!
 - a word written in red on the dial under "SMITHS EVEREST"

It's the Automatic, housing a Smiths 'Imperial' Cal: 10144G 25-jewel, shockproof, nickel finished movement. Double-roller lever escapement with steel escape, the monometallic balance with beryllium balance-spring. Silvered dial with a mix of gilt batons and numerals, gilt hands with red centre-seconds [info - and one available - from the Antique Watch Store]
