Deep Blue has inexpensive dive watches, including some with similar bezels. FWIW I have zero experience with them but their watches are cheap as hell and at least look cool.

My first recommendation if you truly plan to get the Rolex is not to buy an homage in the mean time, you'll never wear it once you get the real deal so you're just flushing money.
If you do, I wouldn't recommend an expensive choice like the Oris. It's an amazing watch on its own, but I have a yachtmaster 40 and I could never see myself wearing the Aquis over it, even though it's gorgeous on its own. I would recommend the Seiko mods that are specifically built to look like a yachtmaster, it's only a few hundred bucks so really you can't lose much when you sell once you get the call.
Something like this you can buy already built for you, or for about his the price you can buy from Ali Express.
