Watchout for the ebay bargains for this discontinued model.
Left is fake, right is real thing.
For me the easiest to notice is:
- glossy Seiko logo on the dial,
- shape and size of the dial indicies,
- dial color (tho, a dial reference number is "00H1 R 2" which was used in the real Alpinist),
- gold frame around a date window,
- both crowns are prety different when you have a closer look.
