Here on the streets of Osaka, I'm seeing Seiko5 models with the 4R36 running around $300 USD and they've been moved from the Seiko5 racks to the glass case next to the "real" Seikos like the SARB. That's with no ISO divers in the lineup yet that I've seen. I'll go hunting this weekend and report back, but I suspect you're going to be looking at a $400 Monster now.We speculate they might change the price, sure. But the 4R36 is reportedly a less expensive version of the 7S26 with the stem connected to wind the mainspring. I say less expensive as those who have seen the movement in other watches report the parts are a bit less glam looking, which wasn't the 7S's strong point anyway.
