Caller Vs. Flyer GMT: How Do You Choose?

Worry not! We’ve done all the digging on caller vs flyer GMT for you. Here’s everything you need to know about the two. 

What Even is a GMT Watch? 

If you don’t know already, a GMT (Greenwich Mean Time) watch is a convenient gadget that allows you to track time in multiple time zones. Just like any regular watch, the hours and the minute’s hands tell you the current time in the zone you’re in. The second (or even third) timezone is pointed out by an additional hand that circles around the dial once in 24 hours. 

If you’re a novice to the hobby of collecting watches, you’re likely to think it’s not much use since your phone is perfectly capable of doing the same. Why even bother investing in a GMT watch, then? But let’s be honest — it’s pretty cool, and the craftsmanship and engineering are truly something to marvel at. 

Let’s take a short trip down memory lane. The need for a GMT watch first arose post-World War II when commercial and international flights became a thing. The first GMT watch was created by a Swiss brand, Glycine — which at the time wasn’t as popular. It wasn’t until Rolex, though, that word got out. 

Caller Vs. Flyer GMT: What’s a ‘Caller’ GMT? 

Now that we’ve brushed up on our basics, what is a ‘caller’ GMT, and why is it called that? A caller GMT, more commonly referred to as the ‘office’ GMT, was designed for your typical businessman. Someone who’s always on the go and is constantly carrying out international business dealings. 

You’re in Dubai and you need to keep track of calls from a business partner or investor in New York? The caller GMT has you covered. All you need to do is set your zone’s time on the primary hands and manually adjust the GMT hand to match the time in your desired zone. It’s pretty simple, really. 

If you’re looking to invest in a caller GMT, you may want to have a look at the Seiko Prospex SPB377. This is a popular option amongst businessmen and we can see why. Not only does it come with a power reserve lasting up to 3 days and a date calendar, but it’s also water resistant to 200 meters. 

What is a ‘Flyer’ GMT? 

Before we can settle the caller vs. flyer GMT debate, we need some insight into what the ‘flyer’ GMT is. This type of GMT has a couple of names, the ‘flyer’, the ‘traveller’, and most frequently, true GMT watches. We’ll get to the later term in a bit. 

This watch is a dream for any pilot and we can already tell why. In functionality, the flyer GMT is the polar opposite of the caller GMT. if you’re someone who’s constantly moving around and never seems to stay in one place for too long, you need to be able to track home time. The flyer GMT allows you to do just that. 

Rather than adjusting the GMT hand on another time zone like in a caller GMT, the flyer GMT allows you to set the GMT hand according to home time. You can then adjust the local hour hand to the timezone you’re in. This makes it incredibly convenient if you need to call home but aren’t sure when’s the right time. 

Our top recommendation for a flyer GMT has to be the Rolex GMT-Master II. It makes for the ultimate cosmopolitan watch. It’s robust, and versatile and can be paired with almost any outfit for that additional ‘wow’ factor. 

Okay, So, Why the Caller Vs. Flyer GMT Debate? 

Caller GMT watches are meant for businessmen (or women, it’s the 21st century!), and true GMT watches are for your flyers and pilots. Why the debate then? 

It honestly boils down to one thing, and one thing alone: preference. Now fans are divided on this one. You’ll find some people who think the office GMT vs travellers GMT dispute is pointless, and then you’ll find others who believe otherwise. 

The debate however is centered around true GMT watches — and whether or not they deserve to be even called that. Some timekeeping fanatics believe that the flyer GMT is the true bearer of the name since it was first designed for pilots. 

While that may be kind of true, it’s hard to ignore the facts. Rolex came out with the first GMT watch, the Master 6452 in 1954. And guess what? It didn’t, in fact, have independent hands! Eventually, in 1983, Rolex rolled out the GMT Master II which came with an adjustable 12-hour hand. 

Here’s something else to ponder: you’ll find flyer or true GMT watches are more widely featured in high-end, luxury brand collections. We’re talking Grand Seiko, Omega, Rolex, and Tudor among many others. In a similar vein, we’ve seen brands such as Mido and Longines make some serious effort in manufacturing accessible flyer GMT watches. Coincidence? We think not. 

So, what even are true GMT watches? We’ll leave that up to you to decide. 

Caller Vs. Flyer GMT: Which GMT to Call Your Own

Now that we know what the two are, the next problem at hand is deciding which GMT watch to pick. Do you go with the flyer or the caller GMT? How do you even decide? The short, sweet and politically correct answer is that it depends entirely on you and your lifestyle. 

Are you the CEO of a successful business that’s always waiting on international calls? Do you work from a fixed location but take calls from all over the globe? A caller GMT will do you good. 

You simply set your main time to your current location and your GMT hand on the time zone you’re expecting a call from. Need to check in with another time zone? No biggie, the called GMT has you covered. Do some simple maths and switch the GMT hand. 

The caller vs. flyer GMT debate would also be incomplete without mentioning that caller GMT watches are considerably cheaper than true GMT watches. You can get a pretty darn charming one for as little as $500. And if you ask us, that’s a steal! 

If you’re a globe trotter, a pilot or anyone who’s always hopping on planes and never finds themself in a one-time zone, flyer GMT watches are your best friend. It allows you to change around your current time zone while staying true to your home (in every sense).
