The minute repeater is still one of the most coveted complications. It is challenging to make, and not that many brands even do so. With the brands that have them in their collection, they more often than not rank among their most expensive offerings. That also makes for quite a catch 22, as the clients buying these timepieces often expect, or even demand, a precious metal case. Unfortunately, have both platinum and gold not the best qualities when it comes to transmitting sound, and are stainless steel and titanium better at it. This has everything to do with the elastic properties and density of the molecules that make up these materials.

The result is that gold or platinum cased minute repeaters, or any other watch with a chiming complication, tend to sound duller and muted than if it was made from titanium or stainless steel. There are ways to compensate for this, for example, by making chambers in the case that resonate the sound better. This does increase the size of the case, and as also these chambers are made from precious metal, they can only improve the quality of it so much. Another option is to improve the gongs themselves.

For this watch, they created sapphire gongs, which give a rather loud and crystal-clear (no pun intended) sound, en in a gold case. Other brands have simply taken an easier route, like H. Mose...
