Rolex Nicknames Explained Teddy Baldassarre

Rolex Nicknames Explained

When it comes to Rolex, nicknames for its watches are almost as plentiful as the watches themselves – and often so esoteric that even avid watch enthusiasts can be perplexed by them. Can you tell a Kermit from a Hulk, for example? Or a John Player from a John Mayer? And would you be able to identify a Thunderbird or a Texano in the rare chance you’d come across one these days? Rolex’s legions of fans have been bestowing colorful and often esoteric nicknames on its most noteworthy watches for decades, and there are more of them than you probably even realize. Here’s a mostly alphabetical primer on the top 20 Rolex nicknames you’re likely to hear (and maybe even use) regularly in today’s buzzing watch-enthusiast community.  Batman GMT-Master II Ref. 116710BLNR Debuting in 2013, this Rolex GMT-Master II reference garnered the nickname “Batman” for its first-of-its-kind bicolor Cerachrom bezel in shades of blue and black, which undoubtedly brought to mind for many enthusiasts the signature colors of DC Comics’ dark-garbed guardian of Gotham City. This “Batman” moniker is now applied primarily to the model on the three-link Oyster bracelet.  Batgirl GMT-Master II Ref. 126710BLNR As alluded to directly above, the “Batgirl” name has been applied to the Ref. 126710BLNR of the aforementioned GMT-Master II, introduced in 2019, which differs from the original “Batman” only in its choice of a Jubilee bracelet rather than an Oyster. Is one more masculine...

In certain very specific situations, one’s life could very much depend on a watch, especially when it comes to environments humans are not good at surviving without support. And this is where tool watches can, literally, play a vital role. Plunging ourselves into the depths of the ocean, for instance, is a fine example of […]

Control. It’s all about control. If you’re not in complete control, others can and will mess things up, and you will be held responsible for it, resulting in a negative image.

Jaeger-LeCoultre Reverso Tribute Duoface Review: Is This the Most Versatile Luxury Watch? WatchAdvice
Jaeger-LeCoultre Reverso Tribute Duoface Review May 25, 2025

Jaeger-LeCoultre Reverso Tribute Duoface Review: Is This the Most Versatile Luxury Watch?

I took the latest Jaeger-LeCoultre Reverso Tribute Duoface Small Seconds for a spin to see if it really lives up to the hype. Is it truly as versatile and elegant as it looks? Here’s everything you need to know! What We Love Fits perfectly, even on my smaller 16cm wrist size! This is a very versatile watch that can suit a variety of occasions and outfits. With its dual time functionality, it is also an ideal travel timepiece. The flip mechanism of the Reverso never gets old, it is just fun to see! What We Don’t The manual wound movement might not be for everyone in today’s automatic world. A 30m water resistance isn’t ideal if you want to use the watch as daily. Price point can be a little high, especially for newcomers to the Reverso family! Overall Rating: 8.6/ 10 Value for Money: 8/10 Wearability: 9/10 Design: 8.5/10 Build Quality: 9/10 The Jaeger-LeCoultre Reverso is a watchmaking icon that was born in 1931, created to meet the demands of British polo players who wanted a watch that could withstand the rigours of the sport. Jaeger-LeCoultre’s ingenious design of a reversible case protected the delicate watch during matches, with the dial being turned over to “hide” from impact. The Reverso blended functionality with Art Deco elegance of the 1930s, leading to a timeless design. Over the decades, the Reverso has gone from being a practical sports watch to a symbol of sophistication, elegance and innovation in the world of horology. Jaeger-LeCoultre’s ...

Longines Spirit Zulu Time 1925 Teddy Baldassarre
Longines May 22, 2025

Longines Spirit Zulu Time 1925

Longines introduced the Zulu Time models to its aviation-influenced Spirit collection in 2022, and the watch’s dual-time complication, stylishly bold design, and undeniable value proposition have made it one of the brand’s biggest hits of the 2020s, spawning additional models in an array of sizes, materials, and color executions. The Spirit Zulu Time is now such a fixture in the Longines portfolio that it almost seems like it has always been there, despite being a relatively recent addition to the lineup; it doesn’t even precede the Covid pandemic, which, of course, somehow  seems like it happened only yesterday and yet also in another time and dimension entirely. However, all of that said, Longines’ history of making dual-time or GMT wristwatches like the Zulu Time reaches back much further - 100 years, to be exact. And it is that century milestone to which Longines pays tribute with the latest member of the family, unveiled today: the Longines Spirit Zulu Time 1925.  Longines Zulu Time History: Longines produced its first “Zulu Time” wristwatch in that eponymous year of 1925, in the heart of the Art Deco era. Very dissimilar to the round-cased modern descendant, that watch had an angular, square case and ornate hour numerals, along with a third hand to indicate a second time zone and, most notably, a Zulu flag emblem with a red letter “Z.” Where did this iconography originate? In military jargon, “Zulu” is the radio transmission articulation for t...

But while its inspiration is historic, the execution is modern and precise: […]

Zenith Defy Skyline Review Teddy Baldassarre
Zenith May 13, 2025

Zenith Defy Skyline Review

While the El Primero movement architecture may serve as the face of the Zenith brand, it is the Defy collection that remains its soul. The Defy represents an historically significant ethos for Zenith, a creative foundation that is just as important to the Swiss brand’s past as it is to its future. Originally meant to be a showcase of innovation and ideas, the Defy collection serves dual purposes: to preserve and celebrate innovations of the past in the “Revival” subfamily, and to continue innovating for the future in the series’ other branches. In 2022, the brand took a big step toward the future of the collection with the release of the Zenith Defy Skyline, a watch that simultaneously looked to build on successful elements of the past and also to capitalize on the integrated-bracelet sport watch trend that had taken hold of the industry. The Zenith Defy collection has roots in the 1960s and ‘70s, when many of the brand’s most iconic and exciting references were released (you can read a more in-depth history here). Many of these have been reborn in the form of modern Revival references, allowing a new generation of enthusiasts to discover them again, or for the first time. These designs weren’t afraid to take risks, from the shape of the case, to the bracelet integration, right into the dial colors and textures. The Defy name quickly came to signify a huge amount of character, and that’s on full display within the brand’s current stable.  In finding a mo...

Hands On: Tudor Pelagos Ultra SJX Watches

Hands On: Tudor Pelagos Ultra

Tudor has been busy expanding the Pelagos collection in recent years, focusing primarily on military and racing associations. But until now, none exceeded the 500 m depth rating of the debut model from 2012. Just launched at Watches & Wonders 2025, the Pelagos Ultra (ref. 2543C1A7NU) can dive to double that depth, making it the deepest diving watch in Tudor’s current collection. The Ultra is differentiated primarily by its headline 1,000 m depth rating and teal accents, and is otherwise a familiar mix of elements from the Pelagos range including the lumed ceramic bezel, a fully brushed grade 2 titanium case and bracelet, and legible snowflake hands. Initial thoughts I personally enjoy overbuilt dive watches, despite the fact that I don’t dive. Practicality aside, there’s just something fun and reassuring about wearing what feels like a vault on the wrist. And that’s what the Ultra feels like – it’s tangibly overbuilt but still wearable thanks to its titanium construction. The biggest, baddest Pelagos yet, the Ultra measures 43 mm and 14.5 mm thick. But it doesn’t look overly large thanks to its 22 mm lug width, which gives it the visual proportions of something a little smaller. That said, the sizing may be too much for some, who would likely find a better fit with the standard Pelagos or Pelagos 39. The dial design is similar to that of the Pelagos 39, with applied polymer-ceramic lume plots. But the Ultra is a little more extreme, with beefier hands and ma...

While the PRC 100 Solar proved tough enough for Central Australia, would it be able to withstand the daily activities of an upper-middle class watch nerd? Let’s find out! What We Love: Elegant, classic design Reliable and robust Wears slim and close to the wrist What We Don’t: The visible solar cells might put some people off Blank caseback — a blessing and a curse Can they add a microadjustment? Overall Rating: 9/10 Value for Money: 10/10 Wearability: 9/10 Design: 8/10 Build Quality: 9/10 Everyone loves a reboot — whether it’s Michael Mann’s Heat, Robert Eggers’ Nosferatu, or Todd Howard’s Oblivion, there’s something magnetic about a classic getting the modern treatment. The watch world is no different. Heritage designs have seen a renaissance, with luxury brands like Zenith, TAG Heuer, and Rolex bringing back beloved models. Timepieces like the Chronomaster Revival Shadow, Carrera Glassbox, and Land-Dweller either faithfully revive past icons or remix archival elements into something fresh. Neo-vintage revivals — more recent classics brought back into production — are also gaining traction. While Omega’s Constellation and Piaget’s Polo ’79 represent the high end, this trend has seeped into the more accessible tier of watchmaking. Japanese powerhouses Seiko and Citizen have often led the charge, but one European brand stands tall among them: Tissot. Part of the Swatch Group, Tissot made waves in 2021 with the PRX, a heritage-inspired hit th...

Tudor GMT: The Definitive Guide Teddy Baldassarre
Tudor May 7, 2025

Tudor GMT: The Definitive Guide

Before getting into the Tudor GMT guide, let's put the brand in context as it has experienced a modern renaissance since returning to the U.S. market with the Black Bay collection in 2012. No longer content as a mere sub-brand of big brother Rolex, Tudor has established itself as the de facto tool-watch manufacture in the $3,000 - $6,000 range, and the brand has done it through methodical progress within the Black Bay, Ranger, and Pelagos families. In 2016, Tudor introduced its first in-house caliber in the North Flag, and has since established its own movements throughout the portfolio, allowing Tudor to approach complications in its own way. Arguably, the most important of these complications is the GMT, which made its modern debut with the Black Bay GMT in 2018. But that’s not the first GMT from the brand.  In this guide, we’ll take a look back at what may be some forgotten GMT references from Tudor, and make our way through the now expansive modern stable of watches boasting the reference today. A GMT is likely the most most requested feature when it comes to new Tudor watches, and lately, the brand has been particularly in tune with those demands - to the point where it’s safe to say that we’re spoiled for choice these days. That’s not to say that there aren’t a few expressions of this complication that we’d still like to see, and I’ll outline some of those in closing.  The GMT complication is a foundational part of the Rolex identity, with Tudor'...
