Railway Worker: Testing the Omega Seamaster Railmaster

While it never flew to the moon or kept time on 007’s wrist, the Omega Railmaster is a practical, straightforward watch to wear on the job. In this feature from the WatchTime archives, we give it a thorough once-over.

The Railmaster measures just under 40 mm in diameter, the same size as the original.

Originally designed for people who work near electric fields, today’s Omega Seamaster Railmaster is a style-confident timepiece with a modern Master Chronometer movement. Its indexes and baton-shaped hour and minutes hands are coated with Super-LumiNova that has a faux-patina color during the day. But when darkness falls, these components glow with a beautiful azure luminescence, while a bright dot leisurely passes the points of the dial’s triangular hour markings. This “lollipop” seconds hand with its luminous disk alludes to the way the seconds are shown on the clocks in Swiss railway stations and underscores the Railmaster’s affiliation with railroading.

When the Railmaster debuted in 1957, it was the latest expression of a longstanding relationship between Omega and the railroads. Omega first delivered pocketwatches to railroad companies in 1895. The Railmaster was the first wristwatch designed specifically for railroad employees, scientists, electricians and technicians who worked in close proximity to strong electric currents. Early Railmaster watches were equipped with a special double case that could protect the movement against the adverse effects of electrical fields up to an intensity of 1,000 gauss.

The dial has elements of both retro and modern styles and is always easy to read.

When a revised edition of Omega’s classic was launched in 2003, the model was already equipped with a modern co-axial caliber that had been developed in the late 1990s. This variation is no longer produced, but the Railmaster returned in a serially manufactured anniversary edition in 2017. It revived the historical design of the original model from 1957 and spiced up the familiar styling with several nuances. Encasing Omega’s self-winding manufacture Caliber 8806, the model had a vintage look juxtaposed with modern Master Chronometer technology, which protects watch movements from magnetic fields up to 15,000 gauss. The Railmaster thereby continues a story that began more than 120 years ago.

Unlike both the original and the limited-edition anniversary model, the dial of the serially produced Railmaster, our test watch, is vertically brushed rather than smooth, thus adding a modern touch to the watch’s face. Nostalgia, on the other hand, is embodied by the aptly named “railway-style” minutes circle, which, incidentally, consisted of elongated index strokes on the original model. By contrast, a more modern impression is made by the numerals 3, 6, 9 and 12, which are present on all models, but printed in different typefaces.

The crosshairs in the center of the dial were understood as a symbol of precision, which the contemporary Railmaster reliably achieves thanks to Master Chronometer Caliber 8806. A COSC certificate proves that this caliber’s timekeeping upholds the official chronometer standard. A second certificate – this one issued by METAS (the Swiss national metrology institute) – affirms that the Railmaster exceeds the COSC’s quality level and, as a tested Master Chronometer, provides protection against magnetic fields up to 15,000 gauss. The Railmaster has a four-year warranty.

Like many other Omega movements today, Caliber 8806 achieves the current highest standards of precision, rate accuracy and resistance to magnetic fields. It doesn’t run quite as perfectly as other Master Chronometers that we’ve tested in the past (see our recent test of Caliber 8900 in the Seamaster Planet Ocean), but it keeps time very well. Our timing machine detected only very minor rate deviations among the individual positions. And our empirical test proved that this watch performs better on a wrist than on the timing machine.

The textile strap, pin buckle, steel back and conical screwed crown are suited for work.

Caliber 8806 has been a three-handed movement in Omega’s Master Chronometer repertoire since 2017. It has essentially the same construction as Caliber 8800, which debuted in 2016. But unlike the 8800, Caliber 8806 doesn’t support a date display. This handsome movement is unfortunately concealed behind the solid metal back of the Railmaster’s case, which has an undulating angular design and is embossed with an image of a seahorse. The seahorse and the lettering on the back always appear in their correct positions thanks to the new, patented Naiad Lock system: this innovation is a kind of bayonet connection for the caseback, which Omega plans to gradually install in all its new models as a replacement for conventional screw-in casebacks.

The case is 40 mm in diameter and resists water pressure to 150 meters (15 bar). The Naiad Lock system ensures that the back always fits exactly, which also contributes to its aesthetic appeal. With a large honeycomb pattern and monumental-looking lettering and engravings, the back also contributes to this watch’s “workhorse” impression, which is further reinforced by the textile strap on the model that we tested. A leather lining on the underside of the strap enhances its comfort on the wrist, while the herringbone pattern of the fabric and the metal grommets around the holes in the tongue recall the robust quality of work clothes.

The Railmaster is also easy to read in the dark.

The Omega Railmaster is inarguably a sturdy fellow. Although its design isn’t especially sophisticated or innovative, this watch has stood the test of time and has proven itself to be a practical, reliable and understated, but still elegant companion that you can enjoy wearing both at work and after the workday is over.

    I bought one. Love it. It’s my explorer or ranger for less money but as much of a watch

  2. Brent S.

    The use of faux patina is excessive. That said, I still want one.

  3. Easely come, marketing: You pay now as much for an O… as for a R…., that much for a L…… as formerly for an O…. Tissot and Certina clear winners. Did I mention the far overpriced US/GB timekeepers?

        Except for the Milgauss being really ugly. Omega > Rolex when it comes to value.

    Are you Kidding?!?!
    A $100 watch, selling for $5,000?!?!?
    They will loose on this watch!!

  5. For ever. These kind of watches are survivors.
    As a tool watch it is a bit highly overpriced. Too highly overpriced.
    My Tissot is a bargain compare to the Omega Railmaster, but keeps time well as a good tool watch. For accuracy my Tissot is no game for the Omega Railmaster master chronometer certified by Metas.

    My Seamaster have the 8800, the one that contain the day window. It is accurate as the Metas certificate promised. So, the quality of the Railmaster is guaranteed.
    But i will go if i want an Omega dress daily watch for a Globemaster. Some extra complications makes it more fun to own.

    In response to the problem, in 1956, Rolex created the Milgauss. The watch was designed to withstand interference of up to 1,000 gauss, thanks to a magnetic shield protecting the movement.

  7. Having owned an Omega master chronometer, I can certainly attest to their accuracy. It ran +/- 1 second a day.
    That shot of the small diameter movement in the relatively modest case makes me sad, however; I much prefer movements to be proportional to their cases.

    Thanks for writing the article. I was a bit confused by the Rate Test Results.
    Is the first number the measured error rate at the beginning of the test (when watch is fully wound) while the second number is the measured error rate after 24 hours from the first measurement?
