It's here. Impressive one-week delivery. It came in a very intricately packaged box with plenty of bubble wrap, plastic wraps, and even a plastic zip-tie thing at the end. Eventually I ended up with this.

I can't solve the mystery of the movement -- you're asking the wrong dude to take the case back off his watch. I will tell you that, in the winding of the crown, it definitely feels like a hand-winding movement.

Esslinger has the correct tools for these. I just use my universal caseback opening tool.

AliExpress has the same tool for less than $4: https://a.aliexpress.com/_dS9ZbCk

Success! Managed to open the case back, though was pretty tough as there was not much for the tool to grip. Anyway this is the movement, which I have no idea about myself.

Just noticed the case back of these new quartz chronograph.
Does it need any special tool? and how hard is it to open with...say locking pilars from a toolbox?

to be safe you might need this tool:

or this

If it requires the $80 tool plus the cost of the handle too I'd rather go to a watchmaker instead.

Thanks for a detailed response. Guess, those folks in Bulova had to come up with creative ideas to make the battery changing difficult for end customer

I am trying to find a similar set of wrenches too. However, a quick look at Taobao didn't give me any promising results. At the same time, I found that Esslinger.com sells something similar:

I wonder anyone here knows if the Esslinger set can be used on common VCMs too?

Thank you very much!

Depending on how tightly the case back was affixed, the rubber ball does not always work. You can get these wrenches in varying sizes at Esslinger:
