One of the common features of the Experimental BR-X1 watch collection from Bell & Ross is the mechanical automatic movement BR-CAL.313 with automatic winding and the strap materials rubber and calfskin. Only the colours of the bracelets vary from model to model. Other common features of these watch models are the case made of shot-peened titanium and ceramic with the characteristic rubber inserts and rocking bar pusher. The back with opening of the case is made of tinted sapphire crystal, centered above the balance. The case of the models in the Experimental BR-X1 collection has a diameter of 42 mm. The case is water resistant up to 100 meters. The watches have a steel buckle. This ensures safety - on land and in the water. And this clasp also has rubber inserts - another typical feature of the models in the Experimental BR-X1 collection from Bell & Ross.
The models in the Experimental BR-X1 collection display hours and minutes using larger hands. The second hand is much smaller and located at 3 o'clock. There is a skeleton date on the dial at 6 o'clock. These chronographs from Bell & Ross also have a 30-minute counter at 9 o'clock on the dial and a chronograph second hand display in the middle. The dial, which in the models of the Experimental BR-X1 collection has different colours, is protected by an anti-reflective sapphire crystal. The applied indices on these models are made of metal with Superluminova(R) inserts. The hour and minute hands are skeletonized, made of metal and filled with Superluminova(R).
