Swiss company TF Est. 1968 is known for making some really cool cufflinks with flying tourbillion fixed inside them. Much like the luxury tourbillion watches, the cufflinks don’t come cheap but are great novelty items for the watch aficionado. The company has added new cufflinks in the Tourbillon range that will be hitting the market this summer as part of a limited edition of 1968 pieces. Named Open Side Cufflinks, the newly added limited edition offerings feature transparent body instead of a stainless steel case which gives its users a better view of the watchmaking movement. Three individually numbered color combinations will go on sale: steel against black, rose gold-plated against black and chocolate brown on a ‘vanilla’ ground and only 1968 sets will be produced for each product reference. The tourbillion trapped inside a steel cage is adorned with carbon motifs. The mechanism is powered by the movements of the wearer’s wrist and encased beneath a sapphire-treated crystal to ensure quality and resistance. The pricing is yet to be confirmed.
