LET'S DIVE INTO

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 SuperLumiNova 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.

DETAIL 2 of 5

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.

DETAIL 3 of 5

THE LUME

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.

DETAIL 4 of 5

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.

DETAIL 5 of 5

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.

BRACELET & CLASP

MORE ABOUT BRACELET & CLASP

Since we started development of Shellback back in 2018 we have created and tried a number of different bracelets. What was clear from the start was the fact that we wanted a so-called "flat link" bracelet. The very first prototype we developed was a flat beads of rice link that pretty quickly was discarded. It was a nice bracelet, but it just didn't feel right.

Back to the drawing board. A sharper, edgier design that fits like a glove with the rest of the case and flirts with the old flat tops was developed. A number of iterations have been made on this bracelet and we are now really pleased with it.

We worked hard with the fit of the bracelet and we quickly decided that we should use fully articulating links that hug the wrist incredibly well. Combined with a diver extension clasp with both micro adjustments and 1,3 cm of "on the fly extension" you have a super comfortable and adjustable watch and bracelet for all wrist sizes.

The edgy and flat design of the bracelet offers a very nice play of light that catches your eye. If you look closely you will notice the polished edge that runs all around the bracelet and harmonises beautifully with the case and clasp that share the similar polished edge.

Shellback is a classic example of a "strap monster". A watch that looks good on basically any strap. To make it really easy to switch between your favourite straps the bracelet is equipped with quick change spring bars, it only takes a few seconds to give the watch a new look – no tools needed.

We are now constructing new female end links that will decrease the overall lug to lug distance and offer an even better fit. Pictures and details of this will come soon.
