Best watch I've ever owned, including pieces that cost 5x more
I owned a Submariner for two years before selling it and buying the BB58. Kept the difference. The Tudor is 39mm which fits my 6.75 inch wrist perfectly — the Sub always felt slightly too large. The movement runs identically (same COSC-certified caliber family), the case finishing is excellent, and the riveted bracelet is genuinely beautiful. Tudor's mistake is that this watch is too good at its price point — it makes the Rolex premium feel unjustifiable. Highly recommend.
Daily beater for over two years
This has been on my wrist nearly every day for over two years through hiking, swimming, cooking, the works. Not a single issue with the movement. The bracelet has developed the usual stretch after this much use and probably needs a service, but that's normal wear. Only gripe: the crown is slightly recessed and a bit finicky to wind. Resale isn't as strong as Rolex but that's honestly not why I bought it. Get this over the Submariner and invest the savings.
