Sorry if this is a total newbie question. I went to put on my Fifty Fathoms and noticed the strap is loose on one corner, what do I need to order please, spring bars and what size? I have never changed the strap on a watch so sorry if this sounds like a really basic question. On the other three corners there is no hole, so not sure if this is a two piece spring bar on this watch?
Photos attached for illustration, you can see the hole on one corner in the first, the other three are fine.
Thanks for any advice given!
