My guess would be no, because of the specifics of the case interface (it's not-quite-straight on the top and curved underneath) but I've not seen it tried. Maybe it could work.
Edit: confirmed that it doesn't fit.
I'm not looking to split though, sorry. Seiko will sell you one I'm sure, but I would guess it's not cheap since they actually put some effort into it and it's a proper five-link with solid end links made from two different machined parts joined together.
Can bracelet be used with Willard spb237 (lugs same20mm), if yes how much and dibs?
