INTRODUCING: The New Tissot Sideral S in three colours

Tissot brings back the Sideral with a fashionable update. 

1969 was a big year for watchmaking. We saw the first automatic chronograph, the first waterproof square watch, the first watch on the Moon, and from Tissot, the world’s first fibreglass watch case in the yachting-inspired Sideral collection. The Sideral was a lightweight and robust watch with an innovative strap-fastening solution.

Fibreglass is a heat-resistant, lightweight, and highly durable material that can be easily coloured. It’s used in aeronautics, sailboats, and Tissot watches. The Sideral had accents of red and green on a black-and-grey dial, paired with a yellow fibreglass case. Today, the brand re-introduces the stylish watch with modern materials in three variants, integrating the colourful look of the original watch with a contemporary design. The design of the new Sideral S is based on the 1971 version of the watch, rather than the original. Read on and you'll understand why.

Now in Forged Carbon  

The new Sideral S is housed in a tonneau-shaped forged carbon case that weighs just 91 grams. Similar to fibreglass, forged carbon has excellent physical qualities, including tensile strength and corrosion resistance. However, unlike carbon fibre, which is usually sheets of woven fibres infused with a resin, forged carbon is created by randomly mixing short, cut-up carbon fibre strands with a low-viscosity resin. The result is a lighter and stronger material with a lower production cost.

The Sideral S comes in three case variations – yellow, red, and blue, achieved by using a coloured resin with the carbon paste. The yellow and blue models have minute tracks in their respective colours, while the red model has a grey minute track. There are additional regatta countdown markings on the dial in green for the first five minutes and red for the next five. The watches also have a black PVD-coated stainless steel bezel that’s unidirectionally rotatable with minute markings, including two regatta countdowns between the ‘50’ and ‘60’ minutes positions.

The hands are white with luminous paint, coupled with a red central seconds hand. On the dial, there’s a date window at the three o’clock position. The three colours are reflected in the perforated rubber straps that are iconic of the OG Sideral, updated with improved quality but bearing the same fastening system. It’s a handsome-looking watch with a 39mm bezel and a case measuring 41mm by 46.5mm. Although it may seem like a large watch, the timepiece wears well on the wrist as the straps are fitted on lug bars that are integrated into the case.   

Alternative strap options for the Tissot Sideral S with quick-changing solutions make the watch a trendy fashion statement.

The funky colours of the watch speak to today’s fashion trends. Tissot has taken this idea a step further by adding strap accessories in green, orange, and black. In addition, you can also opt to mix dials and strap colours to make the Sideral your own. It’s definitely a fun-filled timepiece with an impressive movement behind it – the Powermatic 80 with a skeletonised oscillating weight. Boasting an 80-hour power reserve, the self-winding calibre is equipped with Swatch Group’s patented Nivachron hairspring that ensures even breathing with strong magnetic resistance.  

At just S$1,430 for the Tissot Sideral S, this is an incredible buy for a forged carbon watch case. The Sideral will be available at all authorised retailers from this month onwards.
