Once again watch-insider.com is the very first site to show something absolutely unexpected. Who thought that a Chinese manufacturer would be able to produce a dual-axis tourbillon?
This is what my friend Logan just wrote me in his email. Guys, this is thrilling!!
I’m sending you the original photos, but I’m sorry that the quality of photos can’t be higher now. They’ve been done.
Anyway, it’s only a prototype, I have a chance to photograph the final version of this watch in September and I’ll bring you HD videos at that time.
Besides, they told me that they are working on a petite sonnerie movement (surprising) and a perpetual calendar module. If they can make the prototype before September, I’ll also photograph them.

Dear Logan, the pictures are great. So no reason to worry 🙂
Thank you for this exclusive report and your kind email!
Here is Logan´s report
“Yesterday, Mr. Cao, the head of the R&D department of SEA-GULL, showed me their dual-axis tourbillon prototype. This new model is named WingTourbillon. But honestly, even I don’t know the meaning of this English name.
It is interesting that several years ago, SEA-GULL made some traditional tourbillon watches priced at 5000 CNY (about 800 CHF, amazingly low), but today they are starting to make dual-axis tourbillon.
In the presentation, Mr. Cao made it very clear that SEA-GULL was in the midst of a major shift in their product focus. In the past, SEA-GULL focused on matters such as achieving low price complications. In the future, SEA-GULL wants to be known for high-end watches, and he thinks this dual-axis tourbillon will be a good beginning.
The SEA-GULL factory
The pictured watch is just a prototype and many small details may change in the final version.
The SEA-GULL WingTourbillon
The technical details of the Sea-Gull Wing Tourbillon movement:
Total diameter: 33.8mm
Total height: 6.35mm
55 hours power reserve
The inner carriage rotates a circle every 60 seconds
The outer carriage rotates a circle every 150 seconds
Total mass of tourbillon: 0.68g
Time indicator at 4 o’clock
Power reserve indicator at 2 o’clock
We can see many details from the design drawing of tourbillon. Two axes are perpendicular to each other. The inner carriage is made by Titanium and the outer carriage is made by Aluminum, in order to reach a relatively low weight of the dual-axis tourbillon system.
Total components of the tourbillon system: 137
The transparent back of the prototype
Details of the tourbillon
The engineer told me that the final version of the SEA-GULL WingTourbillon will incorporate Silicon made escape wheel, in order to reach a better weight distribution. In addition, a free sprung system will be incorporated. We can see that in the design drawing of the final version. The engineers of SEA-GULL want this watch with both beautiful looking and accurate timing.
We can find 6 weights on the balance wheel
A Silicon-made flower-like escape wheel can be seen
Another prototype with a slightly different case prototype
The commercially available version will be launched in late 2013, the presell price is 300,000 CNY (about 48,000 CHF, it’s far more expensive than the traditional tourbillon of this brand itself.)
In my personal view, this watch still has a long distance to go before becoming a real so-called high-end watch. The decoration of the movement and the tourbillon cage looks cheap. But remember, this one is only a prototype. The R&D department claimed that they certainly would brush up the designing and the quality.
Btw, Mr. Cao secretly told me that the final version would be produced in September. At that time, I’ll bring more photos and a HD video of this watch to you” …

Logan, this is thrilling!! Thank you very much for sharing the SEA-GULL WingTourbillon with us!
Guys, what do you think? Looks good, isn´t it?
If it functions as good as it looks this is something the Swiss watchmakers might have to fear in the future.
Of course I have not seen the SEA-GULL WingTourbillon and therefore I can not say anything about its timekeeping-performance nor the quality, but still the pictures look not bad.
The only thing I can comment is that the SEA-GULL tourbillon itself looks like the tourbillon mechanism of the Panerai P.2005 caliber, but with the difference that the inner carriage is also rotating. The movement decoration looks very much like the one Jaeger-LeCoultre uses for its high-end calibers.
There is one funny thing to tell here: Since the Panerai Tourbillon P.2005 is not rotating as we expect it doing it from a typical tourbillon, some colleagues and I simply called it the chicken grill when Panerai presented us the P.2005 in Florence some years ago. Even when the Panerai construction is meant to be a tourbillon one could discuss if this is really a tourbillon in spirit of Abraham Louis Breguet.
Yes, chicken grill! Just imagine how a chicken grill turns and then you know how the Panerai P.2005 and obviously the SEA-GULL tourbillon are (rotating) working. Again to mention that in the SEA-GULL execution also the inner carriage is rotating, whilst the Panerai rotates only around one axe.
You think I am cheating or fooling you? Then please Google the Panerai P.2005 tourbillon and you will understand what I mean …
The case of the SEA-GULL WingTourbillon remembers me of the Zenith Christophe Colombe watch …
Thanks to Logan I will be able to keep you updated about further developments coming from SEA-GULL …
Now I am looking forward reading your comments!
