Omega constellation it is worth to buy?

What are your thoughts about it/what has your research shown you?
As a starter, the dial has been refinished.

Poor photos, but the dial has been refinished and the crown is incorrect. You’re not ready to buy a vintage Omega yet. Start here: https://omegaforums.net/threads/learn-how-to-fish.52603/

terrible pictures but I'm not sure that I like that dial at all - the indices look really chunky and the date surround looks a bit basic.

Ok, one more time. First, you aren't going to learn anything if you just post one prospective purchase after another and ask us what we think. You need to do some background learning first (I sent you some sources to start with in my post above), then you need to do some research on your own, then you need to tell us what you think and we'll do our best to help you. We can't tell you much about the watch above anyway because the photos are terrible. When you are ready, the photos that we need to see should be clear, focused and taken in natural light -- at a minimum: dial straight on, each side of the case straight on, the back of the watch straight on, the inside of the case back clearly showing what is written there, and several photos of the movement as well which hopefully show the caliber number and the serial number. Help us help you.

@Dessiner what do you think about the watches you’re posting?
Even if you’re inexperienced, your thoughts/concerns etc will help start a conversation.
