The Chronograph

Measuring 9/10 on the Mohs hardness scale, the TRASKA Chronograph’s synthetic sapphire crystal is virtually impervious to scratches. Colloquially referred to as a “box style” crystal, its design is reminiscent of the plexiglass crystals that graced watches from a bygone era. This particular sapphire crystal also boasts a thick layer of clear anti-reflective coating on the underside — eliminating glare for easy reading even under direct sunlight.

Two transparent rotating discs dominate the dial — minutes on the left, seconds on the right. Stationary lines, printed in red, replace the need for hands. The numerals on the discs float over the lines to reveal minutes elapsed or running seconds at a glance. The minute subdial is linked to the Chronograph function, while the second subdial will begin rotating as soon as the mainspring is wound.

The faceted hour indexes are meticulously filled with Grade A Swiss Made BGW9 Super-LumiNova and then hand-applied with maximum precision. Placed strategically at the 6-hour position, a polished frame surrounds the color-matched date window.

The multi-faceted diamond-cut hands slope up on either side and then taper off to a flat plane with brushed finishing, creating a subtle visual effect that is pleasing even when not consciously registered. Filled with Swiss Made BGW9 Grade A Super-LumiNova, the strong luminescence makes for easy reading even in dim light.

The use of tungsten for the bezel insert creates visual interest while upholding TRASKA’s criteria for formidable hardness — as a common element in ballistics, cutting tools, and aerospace technology, it is prized for its scratch-resistant qualities. A typical tachymeter bezel measures speed from 60 to 400 units per hour. Designed for everyday as well as sporting use, the TRASKA Chronograph is optimized for speeds between 50 and 200 units per hour, a more likely scenario to be encountered in daily life.

The TRASKA Chronograph is powered by the Japanese-made TMI NE86 automatic movement. Amidst fierce competition for chronograph movements, TMI revealed itself as the only viable option for three key reasons.

The first is thickness. The NE86 is 0.3mm thinner than the comparable Swiss chronograph movements.

Secondly, unlike the aforementioned Swiss movements, the NE86 uses a column wheel, a small, vertically oriented wheel with precisely machined pillars or columns around the edges. When the pusher is pressed, a lever advances the column wheel one step. The result is a smoother pusher feel with cleaner engagement and more precise sequencing of the start, stop, and reset functions.

Finally, the NE86 features a vertical clutch that engages the chronograph by pressing two discs together along the same axis — one connected to the running gear train and the other to the seconds wheel. As there is no need for gears to mesh with the chronograph function, and engagement occurs without significant impact, the chronograph can run continuously with minimum damage.

All of our movements are regulated in four positions for enhanced timekeeping tolerances. This process involves manually adjusting the length of the mechanical movement’s hairspring, fine-tuning it to keep even better time than what its manufacturer advertises. After regulation in four positions, the NE 86 series will typically run between -10 to +20 seconds a day and maintain power for 45 hours when fully wound.

Effortlessly adjust the size of your bracelet and get the perfect fit at all times thanks to our tool-less micro-adjustable buckle. With six different positions spaced 1.35mm apart, you can make your bracelet incrementally smaller or larger with the push of a button. No screwdrivers. No screws. No frustration.
