Navy CTS Rubber Strap for Tissot PRX Chronograph

The retail version apparently comes with one extra strap per what I saw on YouTube. This one did not because it was sale. Also this one was missing the pins for the buckle. They gave me two extra spring bars for the lugs instead! The quality and fit are excellent though.

Makes the PRX Chrono wears 1mm smaller but strap has no locking mechanism

I didn't know about this before I ordered it, but caution to anyone reading this, the rubber strap has no locking mechanism. The whole thing is held in place with tension and tension only. This was a surprising disappointment. But the upside is that the design and look or the strap makes the already large PRX Chrono, which normall wears like a 43mm on the wrist with the stock bracelet, wears more like a normal 42/41.5mm now on the rubber. overall disappointed that the high cost of the strap didn't even come with a locking mechanism, but on the upside, it makes the jumbo PRX Chrno wears more compact. take all the user pictures with a grain of salt, since cell phone photos with curvature of the lense makes all watches look bigger on the wrist. in reality, this rubber shrinks the wearing experience by 1~1.5mm. I was already on the fence about keeping my PRX Chrono, this rubber strap gave it a second life. :) I would be hesitant on buying this strap due to the cost and lack of locking mechanism if i knew the lack of and were to do it again.

The best aftermarket strap you can find!

I wanted to have a rubber strap for my PRX Chrono but Tissot only proposes leather straps in addition to the stainless steel ones. I searched online and (luckily) landed on Delugs. The strap came in only a few days. The quality is great and the instructions as well. The butterfly buckle is a work of art. I am super happy with the result.
