I tend to now buy second hand. A few years ago I was buying Omega new at retail or close to retail. Now I would not buy new unless to celebrate some life event (so plan to never sell in which case residuals become irrelevant).
My last purchase was a discontinued Jaeger Le-Coultre Deep Sea Chronograph dating from 2014 (or so) so had to be bought second hand and I am very happy with.
I tend to buy for enjoyment now but Bre&it (sorry to mention the B word) has scuppered buying from the TZ-UK these days - which is annoying as there are some right crackers turning up.
