Favorite Complication

Probably the GMT complication. I like the 4th hand.  

My wife?

GMT and my wife also lol

Cheers!

You own your wife?  I said your favorite complication, not your most expensive. 😂🤣😂

Moon phase for me and world time with a map thingy 🤷🏻

The date, I use mine regularly. 

I certainly don't own her, but she can be both a complication and expensive.

Difficult to choose. In the picture below I have 2 chronographs, 2 GMTs, one world timer, one moon phase, one annual calendar and all of them have date complication.. 

It's complicated.

Sometime I don't want any complications and go for a simple 3 hands watch, which is why I have quite a few 369 watches in the collections. Sometime I want to time meetings, which is where a chrono is handy, and sometime I just feel like I want something that has everything and I pull out the SNA411 with its sliding rule/log dial and bezel (but hey, it has an alarm/dual time zone subdial so it's also practical).

My favourite complication is a ticking second hand ! No day ! No date !!!! . If i want complications i will strap on my GShock !!!! Yeah !!!! I love the elegant plain watch without the Library of Alexandria  printed on the dial !!!! Just as a fellow Cruncher stated “ my two satoshi’s worth “

Probably a minute repeater. Although a well done moon phase is pretty cool as well.

If we are only counting watches I own, then definitely the date. It's on every one of them.

Personally, I really like dial craftsmanship! Materials used, engraving, etc. Not sure if that counts though. If I had to choose a mechanical complication, it would probably have to be retrograde hands!

From the watches I own the jumping hour. Uncommon but very-VERY quick way to read the time at a glance and a little regulator vibe.

I also love the Moonphase complication. Very poetic and (sometimes) so beautifully made. But not in my price range and I assume it's a pain in the a** to set it up everytime the watch stops running.

Me.

Date for me, and yea, day-date too! And I'd really like an alarm - unf. there are few affordable (mechanical) alarm watches, let alone with a decent water resistance. And while I'm at it, compass please :)

1. GMT
2. Date
3. Moonphase

I prefer the look and feel of a three-hander, and it seems my style has always favoured vintage and dress pieces. All my watches have a date, and one has a DD... I also like the idea of a moonphase, GMT, pointer date, and power reserve indicator (the most useful!). I don't particularly care for alarms, but a mechanical watch capable of doing that is really cool, and in my opinion the JLC Memovox in black and rose gold is one of the most beautiful watches of the modern era.

It has got to be a toss up between the equation of time and sidereal time!

Seriously though, chronograph my favourite to fiddle with, but dive bezel is usually most useful for timing things.

I recently discovered that on my G shock square module pressing the top two buttons in world time mode switches the set world time with local time and vice versa, which is super useful when travelling.

I adore moon phases where the moon is painted with human features, especially vintage from 1940s. Glad to see Breitling doing similar recently:

I personally love a small second...but I do not currently have a watch that has one.

Of the watches currently in my collection it is a "jumping hour" (not sure if that is the correct term). I have an old quartz Omega that lets you adjust the hour independent of the minute had. Great for changing time zones or day light savings.
