Watch Complications Guide — Gentleman's Gazette. The accepted definition of a watch complication is simply any function on a timepiece that does more than tell time. This applies to everything from alarms, to tachymeters, chronographs, moonphases, calendars, and anything and everything in between.

In this initial primer, we will briefly introduce some of the more popular complications before providing dedicated articles on each of them as we did with Chronographs. If there is anything you do not understand, please take a look at our watch glossary. For many men, a watch serves as a multi tool capable of providing information in addition to just the time of day. While a watch is certainly viewed as a piece of jewelry, an accessory and a status symbol, for many, it is also a practical tool of the trade that in some cases, has life saving capabilities.

From monitoring oxygen levels while deep sea diving, to measuring the heartbeat of a patient in hospital, watches offer professionals of all industries and trades, tools and functions to assist them in their daily activities. A regulated tool of the trade for everyone from police officers to military operators, the timepiece has enjoyed an illustrious history helping men perform their duties. For someone like myself, I rarely seek out complicated watches for practical use.

While I certainly respect and enjoy such timepieces, my interest in a watch separate from telling time is usually the story behind the watch or it’s exemplary movement. While I do own watches that possess a variety of complications, my favorite watch is a simple timepiece that does nothing more than provide me with the time of day. The reason I mention this is because it needs to be noted that my interests in horology are in the minority. I haven’t bought a watch because I thought it was “cool” since I was ten, nor have I purchased a watch simply based on a complication. I seek rare finds and my primary interests lay in vintage timepieces. Trust me when I say that if I had the money to buy any collection I wanted, most would be let down as none of the watches would be “flashy” or popular among the masses. The fact remains that popular isn’t always what’s best.

Big Macs and Budweiser are very popular but it doesn’t mean they’re any good. This is why, I constantly remind myself to write for the reader, and not for me. And, the odd time I forget, my wife is more than happy to remind me of that. It is for this reason, that I find myself talking about complications and explaining what even the most ridiculous ones do. Not because I have a vested interest in it, but because like Big Macs and Budweiser, most men do. However, I must caution you, that if you’re a collector my advice is to not buy a watch for its complication, but to buy the complication for the watch. Most Popular Complications.

Date Display. Probably the simplest complication, yet also the most useful, the date display is exactly what it sounds like – it tells you the date. This particular display can most often be viewed in four various ways. The most popular of course is the Date Window which presents itself as an aperture next to the three o’clock marking on the dial. Generally this is in the form of two numbers that go from 0- 9 allowing every possible date of the month to be viewed.

In some cases, these numbers will alternate between red and black, in which case it will be referred to as a “Casino” date display. The second most common date display is called a Big Date. This particular display provides the wearer with a significantly larger view of the date which is easier to read at a glance than the Date Window. On some watches, the display will be two separate windows side- by- side with the left going from 0- 3 and the right displaying 0- 9 like the Date Window. While this window can also be found next to the 3- o’clock marking, it can also sometimes be found at the top of the dial beneath the 1.

The third most common type of date display is the Date Wheel which featured a center hand with an arrow or crescent that points to the date strung along the outside chapter of the dial. Often referred to as a “Bankers Dial”, the Date Wheel isn’t nearly as common as the aforementioned forms, but can still be found relatively easily throughout the American and European markets. The fourth most common form of displaying the date is through the use of a subsidiary dial which utilizes a small sub- dial most commonly found over the 6- o’clock mark. Generally used in conjunction with other complications, this dial will rotate clockwise to inform the wearer of the date.

Of course with the constant reinvention of timepieces by quite literally thousands of watchmakers around the globe, there are many different ways a watch can inform the wearer of the date. These four aforementioned methods are simply the most common forms and should not be construed in any way as being the only date displays available on the market.

Day Date. The day date is a slightly more advanced version of the date display. The only difference between a date display and a day- date display is that the day date tells you the day of the week in addition to the date of the month. There are typically two versions used commonly today, the first being the classic day- date dial where the day of the week is present at the top (or 1. The second common variety is a side- by- side window typically found at the 3- o’clock mark, where the day (usually shortened from Monday to Mon) sits next to the date. Triple Calendar. A triple calendar complication is simply a function that adds the month of the year to the day- date display.

Now, in addition to showing the day of the week and the date of the month, the display will also showcase the specific month. A slightly more useless complication, this is really only useful for those so forgetful that they cannot remember what month it is. Rolex Oyster Perpetual Day Date. Annual Calendar. This is a slightly more elaborate and even more pointless calendar function which takes the day, the date and the month, and then adds the year to it. The one note that needs to be taken into consideration, is that it does not account for leap years and will advance to the 3. February every year before jumping to the 1st of March. Perpetual Calendar.

Many people hear the term perpetual calendar and think it’s something more impressive than it really is. While it’s certainly a horological achievement like any complication, the only difference between a perpetual calendar display and an annual calendar display is that the perpetual calendar takes into account the leap year, preventing you from having to manually set the function on March 1st. It should however be noted that this function will require correction in 2. Chronograph. While we’ve already provided a fairly in- depth look into the world of Chronographs, this will serve as a reminder for those who need a quick reference aide. The best definition of a chronograph in layman’s terms is simply to refer to it as a stop watch. Its original intention was to provide a way to time races and while it’s still used for that same purpose today, it has also been used for a wide- variety of other functions. As I mentioned in the Chronograph guide, my favorite story about the Chronograph is the way it saved the crew of Apollo 1.

The first type is referred to as a Mono- Poussier or one- button chronograph. This button is successively pushed in order to start, stop and reset the chronograph function. The only limitation of this type in comparison to its two- button and three- button counterparts is that it cannot measure interrupted time spans.
