Fantastic strap, very well designed. Extremely comfortable. Fits the MM300 case and clasp perfectly. I love it

Es una buena calidad, tiene buen volumen de extensible, los chinos son más delgados y tienen detalles de rebaba... considero un poco elevado el costo pero si vale la pena.

Wanted a rubber strap and still utilize Seiko clasp from the OEM bracelet. This thing looks, fits and feels great and easy to install. Need to buy the orange one now!

Good quality and material and nice feeling on the wrist. My one and only complain that unfortunately kills the whole experience is the length. The short side of the band is too short so someone with a big wrist like me (8.25”) that will use full length, always has the clasp sideways. That could have been avoided if the short side was little longer, making the band easier to size

Love how it fits and makes the watch feel. Takes the top heavy aspect of the marinemaster and makes it very wearable.
