Shellback, a true

strap monster

But, what is a strap monster? Simply put, a watch that you can attach pretty much any strap to and it still looks amazing.

 

For the Shellback release we introduced both a military nylon strap and a tropic rubber strap, both available in black and blue, to match your Shellback.

 

Just like the First Collection all straps feature ”quick change”, no tools needed.

THE DETAILS

DETAIL 1 of 5

THE DIAL

For Shellback we designed a so called sandwich dial, basically a double layer dial with one base plate filled with Super-LumiNova and one top layer with the design. The main markings on the dial are then opened up so that the base layer is visible. A nice touch!

 

The black dial has a beautiful polished enamel dial with white and silver details. The blue dial is brushed with a color that varies from light to dark blue depending on the lighting.

 

A lot of the design elements on the dial are inspired by sea charts. For example the minute rail features a mixture of single, fixed and flashing lighthouse characters that has been slightly modified.

 

Shellback is the first model from Tusenö that is going to feature an optional date window (same price).

 

With the launch of Shellback you can also see our updated logo printed on the dial. Slightly more modern whilst not striving too far from our original design.

THE HANDS

The hands in Shellback share a lot of similarities with the ones in Blackwater but with a few updates to make them even better.

 

The design is slightly thicker and we have added a bevel in the middle of all hands to add more life and reflections. Just like before there is a hole in the hour hand which nicely swipes over the model name Shellback.

 

A generous fill of Swiss BGW9 SuperLumiNova has been added to each hand for optimal glow in the dark.

 

In short, a great design just got even better.

THE MOVEMENT

The beating heart in Shellback is the Swiss Ronda Caliber R150 Mecano. A relatively new movement that competes in the same division as the ETA 2824 and Sellita SW200 (used in Blackwater).

 

We chose the R150 due to the fact that compared to the other movements they have been able to both slim it down by 0,2 mm whilst still adding 40 hours of power reserve. That is actually two hours better than in the SW200 we used in Blackwater. Small changes that make a big difference in the world of watches.

 

If you want to know more about our long time relation with Ronda and the after sale service (which your local watchmaker can do), have a look at the video in the bottom of this page.

THE BEZEL

The bezel inlay in Shellback is made from ceramic, an extremely tough and resistant material that looks great and will stay that way. Just like the sapphire crystal it is close to impossible to scratch the bezel.

 

The bezel will not only look great in daylight but also at night. Every single marker on the bezel is applied with SuperLumiNova giving you a real lume-bonanza.

CASEBACK & CROWN

With the launch of Shellback you will see our new logo but not only that, we have also created a symbol, The Guiding Light.

 

We went back to our roots and looked for inspiration in sea charts. The star symbol is a modified sector lighthouse indicator. A sector lighthouse is a navigational aid that guides ships through a safe channel at night, often through shallow or dangerous waters. It felt like the obvious symbol choice and it also looks pretty good, wouldn't you say?

 

Shellback will be the first model where you will find The Guiding Light both on the crown and on the caseback. Both of which are stamped and both look and feel really nice. In our minds stamped artwork adds a lot of depth and improves the overall feeling.

LUME BONANZA

Shellback will look just as good during daytime as it will during night time. The hands, dial and bezel are all filled with a Swiss BGW9 SuperLumiNova to ensure a good read in the dark (or if you just want to show off).

 

A nice touch in the date versions is the added luminova around the date window to ensure a uniform look.
