I ordered a G10 on Monday, complete with engraving on the back. Within an hour of ordering I received an email asking for some clarification on my engraving request. On the Wednesday, around 48 hours after placing my order, the Roya Mail turned up with my new watch. It's a fantastic, quality watch and the engraving was exactly as asked for.
You can't ask for a better service than that. Well done, CWC. Highly recommended.
