Quick Omega Speedy question

[jasonwongym]

Hi Guys,

Am interested in purchasing a speedy pro. I'm new to the watch purchasing; toh toh chi kau!

I'm planning to get either preowned 3572.50 or a brand new 3573.50

But what's the difference between the 2? The only difference is the movement which one uses 1863 and 1861 right?

Thanks

sorry brand new 357050

only diff is 3572 has a sapphire caseback, and yes 1863 which is same as 1861 without a plastic part.

thanks glampyre! but 357050 also has transparent sapphire caseback too right? or is it hexalite crystal

3570 has hesalite front and a closed caseback.
