Not discontinued but PP are refusing any more orders at the present as they have more than enough on their books to keep their watchmakers busy for a while. Check again in a couple of years. My AD enquired on my behalf so I bought a 5124 which, with hindsight and the pictures in another thread, was the right decision for me. The 5101 would have been too long on my wrist and I reckon the 5124 is better proportioned anyway. The 5124 has become a bit of a 'hot' watch and a waiting list is developing although my AD got me one within a week - pays to be friendly with your dealer.
