Overview: I've worn my Rubber B with the Tang Buckle everyday for over a year.
Fit: Strap fits tight against the watch seamlessly via solid inserts contained within the strap itself.
Finish: Black starts off matte but after a while it gets a nice patina that matches the watch beautifully.
Quality: Smooth thick "vulcanized rubber provides superior resistance to damage and is flexible and strong.
Comfort: Excellent all-day comfort for any kind of activity.
Durability: Time will tell but after one year of daily wear the strap is in great condition - no defects, tears, smells, or allergic reactions.
Comparison: Omega SMP black rubber strap lasted only 1 year of constant use before tears through the tang holes required full replacement.
Company: They stand behind their products and guarantee. I have spoken with them on a couple of occasions and they have been been both helpful and prompt in their response and resolution of my concerns.
Conclusion: I would highly recommend RubberB! To Benjamin, Thank you!
