Shannon it's gonna be a touch decision for me on the next watch. Emperor Tuna is at the top of my list, however I'm craving a Grand Seiko. Been lusting over the SBGH001. Emperor Tunas movement is 8L35 and I have it in my newly aquired MM300... A Grand Seiko would give me the chance to own a movement above the 8L35... I dunno thinking out loud... The GS is not a Tuna though... Hmmm... Either way I have plenty of time to think. The next purchase is a tear or more away... Ha ha.
