Introducing The Roger Dubuis Excalibur Quatuor: Four Balances, Silicon Case, No Tourbillon
Watchmakers have always tried to battle the effects of gravity on a timepiece’s balance assembly. The well-known tourbillon has, to date, been the de facto solution to this problem and we’ve seen multi-axis tourbillons, flying tourbillons, and double tourbillons. At SIHH this week, Roger Dubuis, the avant garde Geneva watch brand, has introduced an effective alternative to the tourbillon, and it’s a world first – a watch movement with four sprung balances.Called the Quatuor and introduced in the company’s Excalibur case, the movement’s balances are paired, two and two, and positioned at 90 degree angles to one another, linked by differentials. Each balance operates at 4 Hz, adding up to 16 oscillations per second. By distributing the effects of gravity across the four balances, these effects are negated, thus resulting in a more consistent timekeeping rate. All the technical detail aside, the movement is quite stunning to behold and the sound of four

Hands-On: With The Blancpain Tourbillon Carrousel, A Combination Of Two Rotating Complications (Live
This year is the 60th anniversary of Blancpain's legendary Fifty Fathoms dive watch collection, but at Basel World we caught sight of something completely different from the brand. The Collection Le Brassus Tourbillon Carrousel takes the aesthetic of the Villeret collection and adds two rotating escapements, a tourbillon at 12 o'clock and a carrousel at 6 o'clock. Not only is the watch captivating to look at, but it also gets more and more fascinating as you begin to notice all the little things that make it exceptional. 2 OF 25 Closer Look At The Blancpain Tourbillon Carrousel First off, it's important to understand what exactly separates a tourbillon from a carrousel, since they can look very similar to the naked eye. A tourbillon uses one source of power to both move the balance wheel and rotate the cage, while a carrousel uses two sources of power, one for the escapement itself and a second to regulate the rotation of the enclosure. These are two

Some AP15400 questions
Don't mind my asking, but I will like to ask existing owners of 15300 and 15400 Royal Oak owners some questions. 1) How's your 15300 / 15400 holding up? Any accuracy or reliability issues so far?2) Does the polishing fade over time or stays brand new? 3) Do you use it as a daily wearer? Is it tough enough for daily wear? While it is undeniably beautiful to me, it also looks kind of delicate. 4) Is it true that the Blue Dial version is more prestigious because it is more rare?5) With the polished surface reflecting light, do you find it too blinky to wear on occasions that a blinky watch might not be suitable, such as formal business meeting, visiting clients etc?6) What will be expected service cost I will be expected to pay be like once it is due for full service? And how's AP's after sales service?7) Does AP warrant availability of parts further down the road like 20 years, 30 years etc?8) If given the chance to repeat the purchase again, will you do it? Or you will choose another br

Aquanaut 5167a Strap Options?
The 5167a comes as standard with a black rubber strap. I see there's also a green strap on a special edition, and possibly a brown strap available as well?Has anyone got photos of their steel 5167 on these straps?Thanks

My New Patek 5990 Flaw...
With all the stories lately about ridiculously long service times from patek and inconsistencies with new watches from the factory, I guess you guys can add another to the list.. Was admiring the movement of my 5990 nautilus yesterday and I noticed a little hair fiber inside the movement. Please see the pic below.. this is really the last thing I care to deal with at the moment, but if I don't send it in for service, the fiber could fall into the movement and get caught in a gear, only to cause further problems. Not impressed at all with patek at the moment. red circle around the fiber.
