1680 - could do with some opinions here...

[bertberr]

Well, I'll keep this as brief as possible, so two main questions:

I've noticed that I can get a nice original red 1680 for 9-10K USD, albeit the less desirable / valuable mk4/5/6 dial version. Or I can get a really nice white 1680 for 6.5-8.5K USD. These are obviously w/o B&P and both examples are at trusted vintage Rolex dealers.

Which do you guys feel would be the better bet longer term (from a value point of view)? It won't be sold by me, and will hopefully end up on my son's wrist one day, together with the rest of my collection, though if he ever decided to sell it, I'd like to think I bought the one that would appreciate the most over a 30+ year period. And before anybody asks, I have no preference one way or the other from an aesthetic point of view.

Secondly, and this is firmly aimed at current or past 1680 owners, was there ever a time when you regretted buying the 1680 over, say a matte dial 16800 with the quick set date? I don't mean from an aesthetic POV - I'm a sucker for matte plexi's, more a practical one - a lot more twirling to set the date if it hadn't enjoyed any recent wrist time.

Use? I intend using it as a daily wearer, rotating it with my 5513 and 30T2. And as I work in a bike (cycle) shop, it will pick up the odd scuff / scratch, so obviously won't be a safe queen!
