Battle of the Icons: Seiko 5 “Gene Kranz” vs. Seiko “Rotocall” Re-Editions

Welcome to the very first Sunday Morning Showdown of 2026! We’re kicking off this year with an exciting match-up featuring two iconic Seiko re-editions. On one side, we have Jorg representing the Seiko 5 “Gene Kranz” SRPL91 and SRPL93, both tributes to the legendary 6119-8460 Sports Diver. On the other side, Daan champions the Seiko SMGG17, SMGG19, and SMGG21 trio, modern takes on the classic A829-6029—better known as the “Rotocall.” Both series have passionate followings, but which one will emerge victorious? That’s up to you to decide!

Why These Watches Matter

Before you question our sanity for this match-up, let’s dive into the reasons behind it. Both the Gene Kranz and Rotocall are not just stylish watches; they carry rich histories that resonate with Seiko fans worldwide. Each piece reflects the design ethos of its respective era. So we ask you: do you prefer the classic charm of the “Gene Kranz,” or the unique flair of the digital “Rotocall”? To sweeten the pot, these watches are priced similarly at €460 and €570, respectively. It’s an enticing choice for any watch enthusiast.

Jorg’s Pick: Seiko 5 “Gene Kranz” Series

Growing up in the 1980s, I have a soft spot for nostalgic designs. Initially, I leaned toward G-Shocks and Swatches, so the Rotocall wasn’t a watch I gravitated towards back in the day. However, the modern reinterpretation of the Seiko “Astronaut” A829-6029 has rekindled that nostalgia for me.

If I were to select a watch that truly resonates with me, it would undoubtedly be the Seiko 5 “Gene Kranz” re-editions. Gene Kranz was not just any figure; he was the chief flight director during the iconic Apollo 13 mission, leading the charge to bring the crew back safely. Daan has beautifully detailed the history behind these pieces, but for those who may not know, Kranz was portrayed in the 1995 film Apollo 13 by Ed Harris, who famously declared, “Failure is not an option.”

The Authenticity Behind the “Gene Kranz” Watch

Interestingly, while Ed Harris sported a Seiko 6139-6002 chronograph in the film, Gene Kranz actually wore a Seiko 5 6119-8460 Sports Diver—an iconic piece loved by collectors. The re-edition boasts a modern touch with options for both white and black dials. Each watch features a striking case design that is a blend of sharp lines and a cushion shape, with the crown perfectly integrated into the case.

The case dimensions are comfortable, featuring a 38.2mm diameter and a 12.3mm thickness, making it easy to wear daily. The combination of brushed and polished finishes further enhances its visual appeal.

Why I Choose the “Gene Kranz”

In this showdown, I have to say the classic looks and captivating history of the SRPL91 and SRPL93 “Gene Kranz” re-editions pull me in more than their competitor. These watches excel as daily wearers, oozing vintage charm while successfully capturing the spirit of space exploration.

Powered by Seiko’s reliable 4R36 automatic movement, I would gladly invest my €460 into the white SRPL91. Owning a piece connected to an iconic moment in space travel history is an immense thrill. With that said, let’s hear about the Rotocall from you, Daan!

Daan’s Pick: Seiko “Rotocall” Series

Thank you, Jorg! Good morning, everyone! Mentioning the “Gene Kranz” and the “Rotocall” together makes perfect sense, especially since their introduction articles ranked among the top three most-read Seiko pieces last year. Both watches are very popular, and I find it quite challenging to choose one over the other. However, today, I’ll make the case for the “Rotocall.”

What draws me most to the SRPLs is their historical significance, particularly their connection to Gene Kranz and the Apollo 13 mission. The soundtrack of Apollo 13 is a personal favorite of mine. While the SRPL91/93 models have rich storytelling, their designs feel a bit understated and, admittedly, generic to me. I like the cushion case, but I lean towards a more dynamic design. The day/date window is not usually my style, although the five-row bracelet is a lovely detail.

A Unique Design with a Dutch Connection

On the other hand, if I had to pick, I would surely opt for the “Rotocall.” Its rotating bezel allows users to switch modes easily, a feature that simplifies navigation compared to the tedious button-pressing in many digital watches. It’s a practical and innovative approach that I wish was more widely adopted!

The “Rotocall” even garnered attention in the astronaut community. Wubbo Ockels, the first Dutchman in space, wore these during his flight on the Space Shuttle Challenger in 1985. In fact, RJ spoke with Ockels, who shared that he carried the Seiko A829-A6019 with him, a version featuring a blue and gray bezel. This makes the re-edition, SMGG21, quite special to me.

Tomas highlighted the challenges in locating good vintage Rotocall examples in his excellent article about the original “Rotocall” from the ’80s. This makes the re-edition a fitting tribute for someone like me, commemorating Wubbo Ockels.

What Could Be Better?

That said, there are areas where the “Rotocall” could improve. Like the “Gene Kranz,” the re-editions stay true to the original in terms of design and dimensions—something other brands could learn from. However, a solar-powered quartz module would have greatly enhanced its practicality. While its battery life of three years is decent, a solar-powered solution would be more convenient. I also feel the unengraved end link on the bracelet detracts from the overall aesthetic, making it seem a touch out of place.

Nonetheless, I’m thrilled that Seiko chose to launch the “Rotocall” re-edition. It’s a quirky timepiece worth celebrating, and those passionate about space travel can experience a piece of history, as the originals were part of over 160 space missions!
