A Trio of Offbeat Wandering Hours Watches to Stand Out at Watch Meetups
From a hot, young Japanese brand to a leading Swiss independent and one of the Holy Trinity of watchmaking
For watch enthusiasts with a curious mind, a wandering hours watch is a must-experience complication. Believe it or not, the wandering hours complication, also known as satellite hours or flying hours, was invented in the 17th century.
The time is displayed along an arc corresponding to 60 minutes. A pointer showing the current hour, from 1 to 12, moves across this arc to indicate the minutes. The display is whimsical yet intuitive, and surprisingly easy to read.
Recently, this unconventional time display has enjoyed a quiet revival. Over the past several months, I have had the opportunity to experience three new watches featuring this historical complication, ranging in price from $5,000 to $65,000. The display is dynamic and engaging, and it achieves this without traditional hands. Even people who are not watch enthusiasts often find it fascinating. These are the types of watches we love to bring to watch meetups, as they easily stand out.
Let’s look into these three intriguing wandering hours timepieces and explore who they may be best suited for.
Otsuka Lotec No. 5 Kai
Otsuka Lotec is one of today’s hottest independent brands. It was founded in Tokyo, Japan, by Jiro Katayama. Due to its ingenious designs, low production volume, and Japan-only availability, Otsuka Lotec watches are highly sought after.
Jiro, a car designer turned watchmaker, has a strong fondness for jumping hours, retrograde displays, and wandering hours. All his models are identified by numbers. The first few models were experimental and never released. The publicly released models so far include No. 5, No. 5 Kai, No. 6, No. 7, No. 7.5, No. 8, and No. 9.
No. 6 features retrograde hour and minute displays. No. 7.5 uses a jumping hour complication. No. 8 combines a jumping hour with a retrograde minute. The No. 5 Kai is a wandering hours watch, or a satellite hours watch, as Otsuka Lotec refers to it on its website.
The look of Otsuka Lotec watches is industrial, mechanical, and purpose-built. They feel closer to scientific instruments than traditional wristwatches. These watches resemble miniature machines designed by an engineer rather than a traditional watch designer.
That is part of the charm of Jiro’s creations. In a modern life filled with mobile phones, laptops, Zoom calls, and AI chatbots, it is refreshing to glance down at the wrist and see a “low-tech” mechanical watch with moving parts that keeps accurate time.
The No. 5 Kai time display mechanism consists of three parts. The first is a set of three discs, each carrying four numbered pointers. The numbers are (1, 4, 7, 10), (2, 5, 8, 11), and (3, 6, 9, 12) for the three discs, respectively. Like satellites orbiting a planet, the discs rotate around the center while also turning on their own axes at the appropriate time.
The second part is an arc-shaped minute track marked for 60 minutes. The numbered pointer glides along this track, indicating both the hour and minute.
The final part is a rotating seconds disc positioned around the 5 o’clock area. The seconds disc stops when the crown is pulled out, allowing precise time setting. During time setting, the dial comes alive, with all three discs moving in unison and demonstrating the ingenious design of the wandering hours mechanism. It is a display I would never tire of watching.
Ethan, a friend and owner of No. 5 Kai, shared the following with me:
“In a market saturated with uninspired clones, the Otsuka Lotec No.5 Kai feels like a breath of fresh air. I’m tired of seeing the same designs recycled with minor tweaks. Katayama has created something with its own DNA — heavily steampunk-inspired, with incredible structural depth and beautiful metallic coldness. It satisfies my favorite indulgence: the act of looking at a watch without actually reading the time.”
The Otsuka Lotec No. 5 Kai is priced at around $5,000, although secondary market prices can reach as much as three times that amount.
H. Moser & Cie Pioneer Flying Hours
H. Moser & Cie is known for its unconventional, sometimes quirky, yet innovative designs. For example, its perpetual calendars are remarkably minimalist and quite different from traditional perpetual calendar layouts. The Streamliner Flyback Chronograph also stands out, with both the chronograph seconds and minutes displayed centrally.
For its wandering hours model within the Pioneer collection, the brand chose a less traveled path as well. In fact, the display could be more precisely described as wandering minutes with jumping hours.
There are four discs in total. The minute track disc sits front and center on the dial, while three-hour discs are hidden behind apertures positioned at 4, 8, and 12 o’clock. The minute track disc has one-third of its perimeter marked with minute indices. At any given time, only one of the three apertures reveals an hour numeral, which points to the minute track to display the time.
The mechanism is based on an instantaneous jumping hour. One hour disappears from an aperture, while the next hour appears in the following aperture. Meanwhile, the minute track rotates continuously to indicate the passing minutes. This results in a display that is unusual, yet intuitive and fun to read.
Here is a sequence of screenshots from a video I took to illustrate how the time is displayed. It is indeed a flying hour!
There are two variants available: the Pioneer Flying Hours White Fumé in steel, priced at 29,000 CHF, and the Pioneer Flying Hours Aventurine in rose gold, priced at 39,000 CHF. The latter is limited to 100 pieces.
Audemars Piguet Code 11.59 Starwheel
Audemars Piguet was among the first in modern times to revive the wandering hours display with the Starwheel collection in 1991. However, the model line was discontinued in 2003. In recent years, examples in various case materials have become favorites at auctions, demonstrating strong collector interest in these whimsical timepieces.
In 2023, Audemars Piguet reintroduced the Starwheel within the Code 11.59 collection with a white gold model. Two years later, a rose gold variant was released. Both models are priced at $65,700 now.
The display mechanism of the Starwheel is quite similar to that of the Otsuka Lotec No. 5 Kai. The main difference is that the minute arc is positioned at the top rather than on the right. In addition, a prominent central seconds hand adds another dynamic element to the design.
For some collectors, the new Starwheel models are a reason to take a second look at the Code 11.59 collection, and I would agree. The white gold version with a blue aventurine dial and the rose gold version with a black aventurine dial are both beautiful and highly compelling.
Jay, an owner of the Starwheel in white gold, shared the following insights along with his wrist shot:
“Having owned the AP Starwheel for about a year, it’s a piece I continually look forward to wearing on extended weekends. It’s quite comfortable on its supplied textured rubber strap and is an instant conversation starter, whether in a supermarket line or at a local watch boutique. What I enjoy most are AP’s unique design cues, which seamlessly blend tradition with modern charm and reflect my desire to feel unique in a world that constantly imitates itself.”
Final Thoughts
I first handled the Otsuka Lotec No. 5 Kai at a meetup organized by 49Crowns, a watch community based in Northern California. The owner had purchased it on eBay at market price, as he simply could not wait for the Japanese independent brand to go global (Ethan, by contrast, was more fortunate and acquired his at retail). I was drooling over it and took many photos. It also gave me the idea for the title of this article.
The wandering hours complication, invented in the 17th century, has certainly stood the test of time. Collectors like Ethan and Jay adore this complication for its ingenious, “hands-free” display of time. It makes the ownership experience feel special and unique. Even after a year of owning the Starwheel, Jay still seemed to be in the honeymoon phase.
We reviewed five attractive models across three different price ranges. Which piece is suitable for whom? For someone who prefers a clean dial or wants a watch for outdoor activities, the Moser Pioneer Flying Hours White Fumé in steel with a rubber strap is an excellent choice.
For buyers seeking an elegant and luxurious dress watch, there are two wonderful options. Both the Moser Pioneer Flying Hours Aventurine in rose gold and the AP Starwheel in rose gold with a black aventurine dial tick all the boxes.
For lovers of micro-mechanical structures, rotating parts, and shining metallic surfaces, the Otsuka Lotec No. 5 Kai is the perfect match. It also carries a strong Japanese artisanal spirit. Unlike most watches that hide the complexity, this creation by Jiro reveals the structures and tiny parts that make the watch tick.
Lastly, the AP Starwheel in white gold with a blue aventurine dial evokes a starry sky in perpetual motion. The overall design is modern, elegant, and understated. It is ideal for someone who simply wants a mechanical masterpiece to enjoy on the wrist.
Which model is your favorite? There is no wrong choice. Whichever piece speaks to you will bring joy, especially when setting the time and watching the dial come alive. It will also become the center of attention at your next watch meetup, almost unavoidably.
For fans of wandering hours or jump hour watches, I recommend following an account on Instagram which is a great resource, @jumphourking
The account is run by Ruud van Rijn, a private collector who owns what might be the world's largest private collection of jump hour watches.
Ruud's expertise is vast and he has given internal presentations on jump hour watches to MB&F, AP, and Urwerk to mention a few.
Of these three, value-wise, the Otsuka is hard to beat, but the AP looks great on you. That Moser just feels... uninspiring 😁
