Companies like Strapcode and a couple others sell bracelets that fit many Seiko models well - particularly for popular divers like the Samurai or Turtle. (I'm only mentioning Strapcode because I haven't purchased bracelets from the other well-known aftermarket companies.)
Not sure about your Seiko, which appears to be a chronograph. I'd be surprised if there is enough demand for a stainless steel bracelet on a chrono for anyone but Seiko to make a bracelet specifically for it. And if the bracelet - primarily focusing on the end links - isn't specifically made for your case/lugs, then it will be hit or miss about whether it will fit and/or have gaps between the end links and case. And I personally wouldn't wear a bracelet with end links that don't fit the case/lugs properly.
Also, whether the bracelet finishing matches the case finishing also could be hit or miss. Here's a picture of a very nice Seiko I have since parted with, which was paired with a well-fitting strapcode bracelet. The bracelet matched the watch well, but under some lighting angles - as in this picture - you can notice the finishing difference. That one photo really captured the finishing difference: it really was not that noticeable 95% of the time. (Lucy, our white Golden Retriever, hardly noticed the difference at all.)
