Nice!
They are quite rare in the West, far more common in the Asian market.
Titoni is Swiss brand that concentrated on China and South east Asia.
Originally the company was called Felco and then did a rebrand for the Asian market, been around a long long time and is as strong as ever today.
Still making the Seascoper, in 2 variants, one with it's own in-house calibre and the other in an ETA.
In China the brand is ranked historically with Rolex, longines and CYMA.
On my first visit to China going into top end high street department stores this was one of the highest featured watch brands.
I had never heard of the brand until I first saw them there and believed when I first saw them that they were a Chinese brand ie Chinese masquerading as Swiss, took me a while to work out that these were in fact legit.
I now have a stash of Titoni's which in the West don't get much financial interest but in China I can easily get 5 times more than I paid!
Still on the lookout for more.
