It's a shame that Tudor discontinued this model in 2021. I think it's an overlooked classic.It does have Tudor’s first manufature calibre, the MT5621. I also love the integrated bracelet. Beautiful everyday watch. Congrats

Grand Seiko is a great choice if you are looking for a brand that offers superior value retention. As I'm sure you already know, predicting the price and direction of a used watch is the same as investing in a stock. You have access to the same background information as everyone else so the best you can do is make a guess based on probabilities. With all that said, just buy a watch if you will wear it and enjoy it. If you get back your money it's just icing on the cake.

It's possible that Seiko could dominate the micro brand market with the movement you are talking about but maybe they should just use a movement like that to keep in their own brand of Seiko and move the whole brand up-market and justify their increase in prices.
