Well, if I may share my two cents...
For me, an awesome watch is the one piece every luxury brand lover needs. I wear my Daytona everyday, all day. The same darn watch. I've had it for years. It was my HG of watches that I patiently waited to arrive. When I look at it today, I still love it, and I want no other watch. I can wear zero jewelry, not even my e-ring, but I always have on my watch, without fail.
There are too many types of jewelry to truly have a HG piece. In the end, wearing different pieces of jewelry is nice because we can, but it really does not matter. We can wear the same piece over and over again... a bracelet is a bracelet. On VCA, I feel similar to you... I am trying to buy more pieces, but for me, it's all the same look to me.
From a fashion perspective, my personal opinion is the watch makes the package.
It doesn't matter what other jewelry is worn or no jewelry at all. It doesn't matter what outfit, dressy or slobby. A fabulous watch, even when worn alone, speaks volumes.
Look at men... In my profession, I work mostly with men, and after hours when we are not with clients, we take off the suits and dress like slobs to meet up for dinner (I travel a lot). Most men do not wear any jewelry. They can look like a slob, yet that one fabulous watch makes a statement.
For me, first priority would be an awesome watch.
I was on the waiting list for two years to get my Daytona. It was totally worth it. I also held out to get exactly what I wanted. A SS with black dial arrived, and it was offered to me. I passed, as I really wanted the white dial. I am so glad I passed. I truly love my old and beat up watch. It's the only watch I want. I did not even want the new black Cerachrom dial version (tried it on, too manly, passed), so I'm actually saving money by wearing the same watch over and over again.

Just my thoughts to help you decide.
