357X vs 311

[OrangeKenny]

Good evening guys,

I’m looking to pick up my first Speedy and could use some help.

What are the key differences between the older 357X series watches and the current 311 series watches? I’ve tried to read some articles but I’m having trouble focusing. Can anyone distill it down for me?

For what it’s worth I’m thinking of a sapphire sandwich.

Thanks in advance

The 311 comes with newer bracelet (has screws now for the extra links) and has extra accessories (straps, loupe, strap-change tool) and a big presentation box. I think that's about it.

Also, 357x comes with hesalite-sapphire (3572.50) or sapphire-sapphire (3573.50).
For 311 I think sapphire-sapphire is the only option for open caseback.

That’s really helpful, thank you!
I’d never heard of the hesalite-sapphire 3572 before. That might be the best of both worlds for me.
