One drawback of baguette diamonds are price and shine. They don't refract as much light as round-cut stones which means that they don't sparkle as much. Plus, since they are usually bigger, they cost a lot more. That doesn't mean they don't shine at all, and high luster is not always what you want. Especially when you want to appreciate the details of a design. Take the beautiful Blancpain tourbillon watch. The case and bracelet use all baguette stones. The dial places the stones in a pattern almost like floor marquetry. You could never do that with round-cut stones. That was probably my second favorite piece of the lot.
Tech specs from Romain Jerome:
Not too much information right now but this is the upcoming limited edition Bremont HMS Victory limited edition watch. The classic looking chronograph will be produced in honor of the historic HMS Victory ship. The HMS Victory was originally built in the 18th century and is the oldest surviving warship from that era. The limited edition watch is said to contain actual original material from the ship itself.
