The Seiko Prospex SPB191 ($ 1,350 on silicone strap )
and SPB 187 are slightly smaller at 42mm , slightly heavier as they are cast in steel , and slightly less expensive due to the aforementioned reasons .
Broader shoulders separate the sister-types , as does a crown migrated slightly south to the 4 o ’ clock position . Other nuances of design define each as the hands , markers , and bezel are endemic to each design . Otherwise these are very similar in the chassis build quality . Available only on a solid link steel bracelet , the 185 and 187 retail for $ 1,200 .
