Technical Perspective: Stopping The Whirlwind: Four Tourbillons With Stop Seconds, And Why That Matt
One of the single most important features of watches intended to keep very accurate time is the presence of a stop seconds function. The single most important purpose of the tourbillon – as Breguet originally conceived it, certainly – is to make a watch more accurate. You would think therefore, in a rational universe, that you would see the tourbillon and a stop seconds function paired frequently, if not invariably . . . but you'd be wrong.First of all, let's talk tourbillon. The basic idea behind the tourbillon is pretty simple: it's a solution to a really old problem in watchmaking, which is that a watch will run very slightly faster, or slower, depending on what position it's in. This is mostly due to how gravity pulls on the balance and balance spring in different positions. For example, think of the balance, which has at its center the balance staff (a very, very thin steel pivot). The tips of the balance staff sit inside the holes of two jewels, and wh

987A Question
This may be a dumb question but, here goes anyway. Could someone give me some insight into the 987A? I am looking for some parts for one and am having a hard time finding many suitable donors. The watch models with that movement seem to go higher at auction than I might expect. I know the 987A was used in a large number of WW2 military watches. But, am I missing something here? Rob

New Arrival - PAM 392
New PAM 392 in the house. I've often considered getting a Panerai, but I could never decide on which one. There's several models that I like a lot for different reasons, but since I'm not in a position to buy more than one, I could never decide which was "the one". That is until now. The 392 incorporates almost all of the things I was hoping to get in a Panerai (e.g. sandwich dial, in house movement, 1950 style case) and does it all in a 42mm case, which is a very versatile and proportioned size for my 6 3/4" wrist. I didn't even know this watch existed until yesterday, and when I tried it on I knew immediately that it was the one for meproof of that is that I had no intention of buying a watch yesterday, but that's how much this one drew me in.I can't say enough about the 1950 case design. I've always liked it, but after spending time with it on my wrist, I have a new appreciation of how beautiful it is. I'm finding it hard to not keep staring at it. The only other watch I've

Squeaky Bracelet
Bought a Rolex Explorer last week and I love it. Over the last few days the bracelet appears to be squeaking. It is probably just requiring a bit of lubrication but any thoughts on how to sort?

Do you use your Submariner bezel as a Timer?
Hi, Curious how many who own Subs (or the Daytona) use them (bezel or chrono) as a timer?I do hear of GMT owners using their design while abroad.Thanks.
