Re: An appointment to buy a watch !
Agreed. Whilst not a 30k Cartier, some years ago my wife bought me a Tag Heuer.
She went to the jewelers without any kind of appointment (gasp!) and spoke to a lovely sales assistant. I believe it might even have been the manager.
She then spent the next couple of hours talking to said assistant whilst handling various different models as each was explained to her.
At the end of the time, my wife chose one, bought it and brought it home for me. Since then I have worn it, and as long as possible will continue to wear it, every day.
I'm pretty sure if she'd been told she couldn't look/see/handle sans appointment, they'd have lost a sale.
After 8 years, it's ready for a service because it's losing a little time now but that's all. No future compatibility problems until and unless some genius rules we need to use decimal time ;)
