Had it a few days now so I thought I'd add a review of my experience so far.
The strap was too long so needed 2 links removed. I called Laings in Cardiff and booked in to have this done on Saturday 4th Jan. Greeted with a cup of tea, the job was carried out perfectly and there was no charge as long as I left them a positive review on Google, which I was happy to do.
Now to the watch.
Lovely on the wrist, I am amazed that the lume lasts until dawn, it keeps great time and several people have commented on it, it's certainly a keeper! Keep your eyes open on the web, I managed to save 拢2200 off list price, I'm sure there will be other deals around. I've bought a rubber strap for it although haven't fitted it yet. I didn't buy a genuine strap as 拢540 for strap and clasp just seemed excessive to me, but aside from the Omega on the clasp it's almost identical to the genuine one.
Now to save for a Seamaster!
