Honestly, the design is kinda good. If this were from Brew, it would be sold out immediately.

I am 100% behind doing whatever TF YOU want to do with YOUR watch. I don't care if you want to wear an Invicta Dive watch on a rope chain around your neck like Flav. Look - it's YOUR watch. The only person who has the right to tell you how to wear your watch is YOU. That being said, I wear leather straps on dive watches whenever I feel like it. Besides, have you SEEN how cool the BB58 Navy Blue looks on a leather strap???

Funny thing… I can’t say how it feels because I bought it for her. However, I can say… she loves it. 🥰

I don’t really know if the choice is as “either/or” as you’ve framed it. Hear me out. I’m going to make an assumption that, since you’re here, and you are considering buying watches in the first place, that your financial position is at least as good as it was when you purchased the GMT Master II. If that is true, then I do think this decision might be more nuanced. That’s not to say that you should be careless with money, just that you might have more flexibility in your approach. If that is so, then here is my recommendation:

Keep the Rolex. It is a fantastic piece that can be a cornerstone of a fantastic collection.

Next, take a good look at the kind of watches you are drawn towards. What do you feel you lack? A dress watch? A field watch? A Chronograph? Take some time to think about that.

When you figure out what speaks to you, look at the world of watches with an open mind. There are watches at every price-point that can scratch any number of itches. I have $300 watches that are tougher than almost anything else in my collection, and I own Rolex, Breitling, and Omega dive watches. My point is, you might not be limited to the price-range you are thinking about. If you find that you come across some watches that speak to you in other price-tiers, maybe give them a shot. There isn’t any reason you have to spend a lot to enjoy the hobby - or anything for that matter.

Ultimately it’s your decision, but maybe take a moment to look at the rich field of choices before narrowing down your choice to keep/sell.

I have a 124060 (No date Sub) and a white dial SMP. Both are nice watches. However, the bracelet on the Sub is better. Does that make it worth the almost 2x price? No. However, on the topic of bracelets, of Omega would add 2mm of taper to the SMP bracelet, it would probably be enough to make the roughly 50% cost undeniable - especially against Tudor. But, that’s just my .02.

I have a Grand Diver, and I think that they are a great watch for the money. Especially if you have the wrist for it or you just like a bigger watch. Solid end-links, milled clasp, 300m WR, and great construction (I mean, the bezels line up, [cough, cough]). I get why people hat on Invicta - they have some hideous models, but the Pro Diver and Grand Divers seem to be just fine. Plus... like you said - Seiko movement.

Definitely get what you like. Personally, I love blue dials. However, some watches just look good in white. Longines has a “Big Eye” Chronograph, which has a stunning blue dial (they call it “petroleum“) which is textured. It just works. This watch looks great in blue, but in my opinion, in blue it reminds me of an IWC. That’s definitely not a bad thing - IWC are amazing watches. In white, I feel like this watch is in its element - particularly if you are interested in dressing it up. When I bought my Tank XL, I got it as a dress watch, and specifically because of the silver-white dial. If you look at other higher-end makers, many of their dressiest pieces also feature light dials. The Saxonia, Calatrava, and the Patrimony have white dials on the dressier expressions of those pieces. It’s definitely not a rule, though. Also, consider that white tie and jacket is considered more formal. But, these are archaic rules, and you can do whatever you want these days. I mean, I literally don’t think anyone besides the most hardcore watch+style enthusiast will care that you wore a watch of any style to a formal event (during an era when a reasonable amount of Americans still either knew or cared about such things, Hollywood still chose to put a Sub on James Bond’s wrist - on a {clutch the pearls} NATO strap, no less!). Most people today won’t even notice the watch, and even fewer would know what to say (style-wise) in those circumstances anyway. So… unless you live at Downton Abbey, and you have footmen and a valet calling on you regularly, do what pleases you, and don’t listen to any of us. You do what makes you happy. 😊
