The Minute repeater is slow, takes nearly 30 seconds for the 12:59 sequence. A Patek Philippe takes around 18 seconds.
Also, the MR has a very noisy governor, so if you put your watch to your ear, you hear a lot of background noise from the spinning governor. It's also a very thick watch. Layer cake movement, not a true integrated movement, hence giving it a full thickness. Although admittedly, the Patek Philippe watches are not fully integrated either, still mostly modular/layer-cake style, but they're at least thinner.
