I recently bought Seiko HBF001 the watch is fantastic, hugely impressed with the case finishing, overall quality (the new bracelet with micro-adjust is exquisite) and the accuracy of the movement is incredible. This is a lot of watch for relatively low price point compared to alternatives. Seiko are definitely punching above their weight with this new offering!
The watch wears smaller than the 42.6mm case size would suggest, I have a 16.5cm wrist and I think it fits me well.
