The Haim Annum, a New Annual Calendar, is the Brand’s Most Ambitious Watch Yet

The Chicago based brand Haim celebrates their five year anniversary this year with what is certainly their most ambitious watch to date, the Annum. When brand founder Zakir Miah showed me an early prototype of the watch months ago at a Windup Watch Fair, I was surprised and impressed that he would even think to attempt making a watch with such a niche complication. It resets the brand in some ways, and will likely force people to consider Haim in a different way.  As surprising as an annual calendar from Haim is, if you pull back far enough, there were signs that Miah wanted to move the brand into a slightly higher end and more refined direction going back a few years. The Legacy Automatic, for example, featured a custom decorated movement by an American company, Maryland Watch Works, and the whole watch was a significant step up in terms of finishing and build quality compared to prior efforts. But the real shift came with the Viajero Worldtimer released last year. This watch featured a rather clever modification of a common Seiko-made GMT caliber, replacing the hand for the second time zone with a cities ring akin to what you’d find on a classic world timer. The old-school “globe” dial was meant to recall the most famous worldtimers from the Jet Age, and while the Viajero doesn’t have nearly the watchmaking complexity of those timepieces, it was able to mimic the style of those watches to an impressive degree when you consider the price tag of $799. The Annum ar...

What is a Rehaut on a Watch Dial?

Most parts of a watch that you’ll encounter in your pursuit of horological knowledge are names that are fairly familiar and mostly self-explanatory: case, dial, hands, movement. (We run down the gamut of the most important watch parts in this article). But now and then, you may read about, or hear someone referring to, a watch’s rehaut - a somewhat intimidating-sounding French term that might give you pause at first. What is a rehaut, and what is it used for? Read on. Put simply, a rehaut (properly pronounced “Re-OHH” without the hard “T” sound at the end) is the French word for “flange,” which is the English term most often used in its place when discussing watches. It describes the rim between the periphery of the dial and the crystal. Unlike dials and cases and hands, not every watch has one. But for many of those that do, the rehaut is not only a frame that fills in the space between the dial edge and the crystal but also a utilitarian element that can add interest and even useful information to the dial itself.  Some watchmakers use the rehaut for staging the hour or minute markers, In the case of chronographs, like the TAG Heuer Carrera featured above, the rehaut can provide a spot for added functional markings like a tachymeter scale (which can use the built-in stopwatch to measure speeds relative to distance) or a pulsimeter (which works with the chronograph to measure heartbeat rates). Other watches might use the rehaut for calendar indications ...

The Rock Watch is Back, and We Smell What Tissot is Cooking

Stone dials, as we’re all aware, have been having a moment over these last couple of years. Time, I suppose, will tell if the prevalence of stone dials across more affordable price ranges is a trend, or just a new part of the watch landscape that we’ll all just accept and live with, like green dials, or carbon cases. With the renewed popularity of this inherently 1970s/80s inspired design cue, it was really only a matter of time before we saw the return of a watch that takes the use of stone to a different level entirely. The Tissot Rock Watch, an artifact of the 1980s if ever there was one, is back, albeit in a limited edition that might be tough to acquire depending on your geography (more on that in a bit).  First, a little background on the Rock Watch. Launched in 1985, Tissot claims that the Rock Watch was the first ever watch with a case and dial made entirely from granite procured from the Swiss Alps. I’ll admit here that I haven’t done a ton of scholarly research on the topic, but I’m willing to take Tissot at face value here simply because granite is a particularly difficult material to work with, requiring highly specific machines and tooling. It’s a watch that doesn’t make a ton of practical sense from a production standpoint, but naturally was quite popular in the mid 80s and eventually spawned an entire collection for Tissot that featured a huge variety of exotic stones. Original Rock Watches from the 1980s The new version of the Rock Watch rema...

What is a GMT Watch? Teddy Baldassarre

What is a GMT Watch?

GMT watches, and other types of watches with useful complications for travelers, are enjoying a surge of popularity these days, with watchmakers large and small stepping up to produce travel watches with both user-friendly mechanics and attractive design, at a variety of price points. Yet, if you’re new to the watch game, you still might be a bit curious about what is a GMT watch, how to read and set them, and how one style differs from another. In this feature, we attempt to address all the pertinent questions you may want answered before purchasing a GMT or any style of watch with the ability to show multiple time zones. What is a GMT watch? GMT is the abbreviation for “Greenwich Mean Time,” the system of world timekeeping based on the calculation of mean solar time from the Royal Observatory in Greenwich, London. Established in 1884 at the International Meridian Conference, the Prime Meridian was conceived as a straight line running from the North Pole to the South Pole directly through Greenwich, serving as the point of zero degrees longitude from which 24 separate time zones divide the Earth: the Eastern Time Zone of the United States, for example, is designated as GMT -5 (i.e., five hours west of Greenwich, which is GMT 0). A GMT watch is essentially a timekeeper designed in that same utilitarian spirit, allowing its wearer to read the time in at least two time zones simultaneously. Many such watches actually use the initials “GMT” in their model names, whi...

Fratello Talks: Trade To Upgrade - Is It Possible To Trade Your Way To Your Grail Watch?

Everyone knows the story: you start with a paperclip and trade your way up to a house. Canadian blogger Kyle MacDonald made it happen in 2006 with his One Red Paperclip project. Could this principle, on a smaller scale, be applied to watches? Today on Fratello Talks, Nacho, Thomas, and RJ join to discuss the […] Visit Fratello Talks: Trade To Upgrade - Is It Possible To Trade Your Way To Your Grail Watch? to read the full article.

What is a Chronograph Watch? Teddy Baldassarre

What is a Chronograph Watch?

Chronograph watches are among the most popular styles of timepieces: iconic models like the Rolex Daytona, Omega Speedmaster, TAG Heuer Carrera, and Breitling Navitimer, for example, have become some of the most famous and collectible watches in the modern era and have contributed to the enduring appeal of the chronograph to generations of enthusiasts. If you're new to the watch game, however, you might be wondering not only what all the buzz is about but what these watches actually do that makes them so special. Read on for a comprehensive primer on chronograph watches, from their earliest ancestors to the most ambitious, avant-garde timekeeping technology available in chronographs today. Chronograph vs. Chronometer As I explore in depth in our guide to chronometers, one of the first hurdles to clear for newcomers to watch appreciation is the clarification of two very common horological categories: Chronometer and Chronograph. Quite simply, a chronometer (from the Greek chronos, meaning time, and meter, meaning measure) is any watch or clock that keeps reliably accurate time, usually as determined by an outside independent testing agency, whereas a chronograph (from chronos and graph, i.e., to “write time”) is any watch or clock with the ability to track and record intervals of time, aka a stopwatch. The terms are not interchangeable but they are also not mutually exclusive: a watch equipped with chronograph functions can also be a chronometer if it has met a s...
