Hi Kenny, I have the same watch and using it on my travels in the UK. Very handy watch great to wear and super easy to read, that is the the analogue part. The digital readout is not that easy to read. I have a similar citizen model watch is really easy to read digitally . But I much prefer the Seiko with its quality appearance both on the the bracelet and the black strap of which I have both. Cheers for now Tony
