I received the Monster strap in a timely manner.  It is what I was looking for to replace another rubber strap on a 25+ year old Seiko Sports 150 yachting timer.

It did NOT come with the advertized Spring Bars however -- and that is the reason for the mediocre rating of 3 stars.

Update

I contacted by phone the supplier -- The Watchband Store.  He is immediately putting the Spring Bars in the mail to me and he apologized for the error.  Great customer service -- and I have updated the rating to 5 stars.
