WISeKey in cooperation with Lexing Switzerland by Sebastien Fanti, to 
launch the Non-Fungible Token (NFT) auction of the Swatch Space Shuttle 
STS -- 75, the first Swatch WristWatch on a spaceflight mission, 
connecting the watch with an orbiting satellite 
 
   The Swatch Space Shuttle STS -- 75 will launch will be on May 18 and 
will include the connection of the historical Swatch with a satellite 
currently orbiting the earth. The satellite will send a unique Key 
encrypted by WISeKey that will generate the digital identity of the 
Swatch to be physically inserted on the watch box using a WISeKey 
Microchip. This operation will be done publicly during a webinar with 
space industry leaders that will witness the first evert NFT generated 
from the Space. 
 
   GENEVA, -- April 27, 2021: WISeKey International Holding Ltd. 
("WISeKey") (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, 
AI, Blockchain and IoT company, today announced that it has joined 
forces with Sebastian Fanti to launch the Non-Fungible Token (NFT) 
auction of the Swatch Space Shuttle STS -- 75, the first Swatch 
WristWatch on a spaceflight mission. 
 
   In order to celebrate this event, Swatch manufactured 1100 Access To 
Space Access Swatches. 100 of the Access To Space Access Swatches were 
taken into space onboard of the American Space Shuttle flight STS-75. 
The Swiss astronaut, Claude Nicollier, will go into space wearing the 
Access To Space Access Swatch on his wrist. Claude Nicollier was a 
member of the first group of ESA astronauts selected in 1978. He joined 
Group 9 of NASA astronauts in 1980 for Space Shuttle training at the 
Johnson Space Center, Houston, Texas, where he was stationed until 
September 2005. From 1996 to 1998, he was Head of the Astronaut Office 
Robotics Branch. 
 
   The launch of the Swatch Space Shuttle STS -- 75 is scheduled for May 18 
and will include the connection of the historical Swatch with a 
satellite currently orbiting the earth. The satellite will send a unique 
Key encrypted by WISeKey that will generate the digital identity of the 
Swatch to be physical inserted on the watch box using a WISeKey 
Microchip. This operation will be done publicly during a webinar with 
space industry leaders that will witness the first evert NFT generated 
from the Space. WISeKey NFT capability uses a patented method for 
digital certification of authenticity of a physical object, and 
corresponding computer program and storage device, as well as using the 
method for digital certification of authenticity of a physical object of 
value. The method includes the steps of issuing a storage device, 
including a digital certificate of authenticity including encrypted 
information reflecting at least one characteristic unique to the 
physical object, checking, whenever required, the validity of the 
digital certificate of authenticity by use of a network computer, the 
network computer cooperating with the storage device and a validating or 
a certifying authority so as to output sensibly in real time the status 
of validity of the digital certificate of authenticity, and modifying , 
whenever required.   More information about the patent can be found at -

   With a rich portfolio of more than 46 patent families, covering over 100 
fundamental individual patents, and another 22 patents under review, 
WISeKey continues to expand its digital tangible asset protection 
technology footprint in various domains, including the design of secure 
chips, near field communication (NFC), development of security firmware 
and backend software, secure management of data, improvement of security 
protocols between connected objects and advanced cryptography. 
 
   WISeKey's patented technology that already secures millions of objects 
(luxury products, expensive wine, jewelry, collector's items, high end 
watches, art, etc.), now includes NFT applications backed by Digital 
Identification technology that secures, authenticates and proves 
ownership of digital and tangible assets. The combination of Digital 
Identification with NFT will be a game changer in proving ownership of 
digital tangible assets. Major brands are already creating and trading 
NFTs: Nike has used them to create digital shoes linked to real-world 
shoes while Louis Vuitton uses NFTs to track the provenance of luxury 
goods. This trend is likely to continue in 2021 as fashion embraces the 
trend towards representing physical assets in a digital form. Imagine an 
asset, such as a luxury watch or famous artwork that need to be 
authenticated, the NFT digital asset can be used to prove the ownership 
of the virtual and tangible object containing digitally signed 
information that is easily verifiable, making it impossible to 
replicate. With this technology creators can turn their products into 
NFTs for copyright ideas. The use of NFTs to verify identity involves 
turning physical objects into non-fungible tokens to avoid counterfeits. 
 
   This technology has received a patent in the USA
