I just got a Scurfa Diver One with yellow dial and PVD case. As you can see below, it comes with a black rubber strap.

However, with the black bezel, black case and black strap, I think it's a bit too much black, so I'm thinking of getting a strap with yellow stitching to add some variety.

I've narrowed my choices down to

1) A Strapsco black rubber strap (middle image) that's $18, and

2) A Hirsch Robby with leather top and rubber lower surface, that's currently going for $90. (bottom image)
When I checked a few days ago it was over $100.

What do you think?

a) Keep it as is with the original all-black strap,
b) Get the Strapsco
c) Splurge and get the Hirsch Robby
