In Jurassic World: Rebirth, Jonathan Bailey takes on the role of Dr. Henry Loomis, a paleontologist-turned-survivalist—marking a sharp contrast from his more refined 19th-century portrayal as Viscount Anthony Bridgerton. This time around, there’s less romance and more chaos, with blood and danger taking center stage as prehistoric predators return to wreak havoc in this Hollywood blockbuster.
The film showcases Bailey in full action-hero mode: rappelling down rocky cliffs, facing off with raptors in shadowy caves, and wrestling with aquatic monsters. In a world where T-Rex encounters are a daily hazard, you’d better be equipped with serious gear—including the right timepiece. For Bailey, a proud Omega ambassador, that meant choosing a rugged, no-nonsense watch for the part.
“For Jurassic, I wanted to put an Omega watch through its paces. I knew that I wanted my character to wear one and I spotted the Railmaster from '57,” says Bailey. I spoke to Raynald [Aeschlimann, Omega CEO] and he tracked down a watch that was made in homage to that exact watch. So I wore that in all different experiences.”
Bailey had his pick of the Omega lineup, but the Railmaster stood out for good reason.
“The original Omega Railmaster goes back to '57 and was developed to be a tool for scientists,” says Fratello’s Robert-Jan Broer, “so it’s an excellent choice for a scientist in Jurassic World! Precise timekeeping in labs or other places where external factors could be of influence was important, so a highly anti-magnetic and water resistant watch was a necessity!"
For the film, Bailey wears the 60th Anniversary Railmaster, released in 2017 as part of Omega’s tribute to its legendary 1957 trio. To better match his character’s rugged, hands-on vibe, the watch’s stainless steel bracelet is swapped for a more utilitarian leather strap. Paired with Loomis’ practical wardrobe—plaid shirts, chinos, and worn leather boots—it looks perfectly at home in the world of dino survival.
Broer adds, “The 2017 edition keeps the aesthetic of the original CK2914 but benefits from modern technology. Instead of the old Faraday cage construction used to block magnetism, this version uses advanced anti-magnetic materials in the movement itself. That gives it superior performance without compromising the tool-watch appeal. It still looks tough, understated, and perfect for work in the field.”
Here’s some background: the Railmaster is part of Omega’s famed 1957 tool watch trilogy. While the Seamaster was made for divers and the Speedmaster for race car drivers and astronauts, the Railmaster was tailored to those working around strong magnetic fields—railway engineers and laboratory scientists. Technically, the Railmaster was launched under the Seamaster banner, but its focus on anti-magnetic capabilities made it distinct. With resistance up to 1,000 gauss, it protected against one of the main threats to mechanical watches: magnetism, which can cause significant timekeeping issues.
Though technology has evolved and most modern watches offer decent magnetic resistance, in the late 1950s, this was cutting-edge watchmaking. The original Railmaster was only produced for a few years, which adds to its rarity and desirability among collectors today.
Stan Duin of Vintage Masters puts it simply: “The Railmaster is the perfect match for Dr. Henry Loomis. It’s durable, practical, and engineered for precision—exactly what a paleontologist would need. Its anti-magnetic construction and no-frills design make it a great companion in the field, but it’s also stylish enough for everyday wear. It’s a watch made for exploration and discovery.”
So while it may be tough enough to survive a dinosaur chase, the Railmaster doesn’t scream for attention. It’s a versatile piece you could just as easily wear with a blazer, jeans, or your everyday casual look. In short, it’s the kind of all-purpose watch that just works—whatever the scenario.
Unlike the Seamaster, which has James Bond credentials, or the Speedmaster, which went to the moon, the Railmaster doesn’t come with that kind of pop culture endorsement. But it’s precisely that understated quality that makes it so compelling. It's a reminder of Omega’s technical legacy—an innovative tool watch made with professionals in mind. That authenticity gives it serious appeal among seasoned watch collectors.
Jonathan Bailey connects to that legacy on a personal level. His introduction to Omega came through his grandfather, who owned a vintage De Ville. That connection to heritage and time passed down through generations makes his choice of watch for Jurassic World: Rebirth even more meaningful.
“There’s something powerful about a watch that gets handed down,” Bailey says. “As I get older, I think more about legacy, about how we spend our time and what we leave behind. A watch like the Railmaster captures that—it’s built to last, to be used, and to be remembered.”
