Well they have quite different personalities but if I could only keep one it’d be the black. Wear it every day and quite under the radar. Good choice with the SD43. How do you find your Pepsi? Jubilee comfortable?
The Ceramic Pepsi GMT II is nice, but it's a bit more elegant with it's jubilee bracelet than my previous BLNR. So, it's less sporty and less of a daily wear watch, and doesn't fly as under the radar as my BLNR did.
It also seems to wear smaller than my previous BLNR, maybe due to the bracelet, and the bracelet seems to taper more at the clasp than I would like. The comfort is not much different from my old BLNR, and accuracy is about the same at better than 1/2 sec/day within Atomic time.
At one point (before Pepsi) I had the opportunity to buy a brand new white gold Pepsi with Oyster bracelet at 35% off, as my Rolex AD was moving and needed to get rid of inventory. To pay off the purchase, I would have to sell my 42mm Polar Exp II + BLNR + TT Blue Sub. But the idea of giving up 3 Rolex for 1 gold Rolex was frightening to me at the time, and so I offered to buy it outright at 40% off and then sell my other watches to pay it off. I figured for that price, I'd take the risk, but they were firm at a 35% discount. I liked the look better with the oyster, and I liked the warmer color tone of the gold, so it could have been my one and only Rolex.
I have wide flat wrists, at almost 7.5", and so the Pepsi GMT and my Hulk seem to wear slightly small for a guy that is used to wearing a 45.5mm Ti Planet Ocean 9300 most days. The SD43 and the Deep Blue are more my size, but the Hulk wears better on my wrist than the Pepsi GMT, although still feeling slightly small. So, I occasionally wonder why I didn't just stick with the 42mm Polar Explorer II as my primary GMT watch, and save the money. On the other hand I like being part of an elite group of people with a hard to acquire watch.
I love the ceramic Daytona (white very attractive but black looks bigger to me). But I worry that it would also wear too small on me, since I tried a YG Daytona and a white dial SS bezel Daytona and they were small. If I could get one for MSRP I'd maybe give it a try, but I've been on the list at both of my local Rolex AD since the watch was announced and still haven't gotten the call to pick one up. I stay in touch with them, but they know I won't buy anything else since I have to save my money for the grail.
EDIT - this video shows how much smaller the Daytona is when compared to the Speedmaster Pro
