Reasons not to buy from Jomashop?

I bought form them on the past without a problem. I did have trouble re-selling a watch after that because some buyers didn't like that it was gray market to begin with.

Watches where fine. Their return policy is a little aggressive.

If it's a watch you like and want to keep get it.

This said, I would try some of the trusted sellers like @Kringkily who can sometimes source at the same price with a great amount of confidence,

My Speedy is from Joma and it's been fine.

Do they hold the warranty and service it through Omega on your behalf, or do they open it at Joma?

They do it themselves.

Isn't Chronext basically the same price after import duties/taxes, but comes WITH the Omega warranty too? Why choose Jomashop over Chronext?
