Replace movement in Citizen divers, advice and recommendatio

[Dr Bob]

Hi all,

I've got a citizen divers watch which was inexpensive, but I really like it apart from the fact it loses about 5 minutes over a week, is it possible to replace the movement with something that's going to keep better time and does anyone have any recommendations for someone that offers this service?

I'd also like a good quality NATO strap to go with it... I've got a rather 'thin' (if you see what I mean) NATO on ATM... and is assume that any eBay /amazon sourced replacements will be equally disappointing

Ok, I realise it's a cheap watch (I think it was about 140 quid) but because I bought it on my honeymoon, it's something that I have an emotional attachement to, and I'd like to give it a freshen up.

Thanks in advance all, CH
