Omega

I'm really starting to love the look of my 321 on this black and red barton silicone strap! The only thing that bothers me is the bad finishing on the buckle, but the strap itself is really well made and comfortable. ...  

Maybe you can find a watch repair shop to fix this?

That could be a good idea actually...

Nicest watch / strap combo I’ve seen in a while. For some reason the Speedmaster seems to lend itself to creative combos more than Seamaster. Absolutely worth getting the buckle right and perhaps Frankenstein in an Omega buckle?

The red makes it feel like a racing themed watch. Super sporty. I'll try to work something out with the buckle for sure!

19mm always makes it harder to find options

I got them for my bracelet version Chronoscope and I’m not switching back anytime soon. ...  

I love it because it is smaller and, while it looks like a regular speedmaster to the untrained eye, it conceals the 321 inside

Perfect for our current heatwave!

Exactly, rubber is perfect during the summer months, plus it fits with the rest of my collection since both of my Omegas are on rubber straps. A theme within a theme, or maybe I'm just obsessive 😅
