The appearance of the Tutima Military Chronograph, Reference 798, is largely determined by its outstanding professional characteristics. On the one hand, there is the movement. Tutima has deliberately chosen self-winding caliber 5100 by the reputable Swiss movement manufacturer Lémania. It ranks amongst the tried-and-tested classics in the select range of Swiss chronographs.

Over the past few decades, it has passed countless endurance tests with flying colours. Its robustness, reliability and precision under even the toughest conditions are partly the result of its ingenious design, which reduces the number of components to a minimum without impairing the functions in any way. These bare essentials are planned to last throughout a long working life.

The absolutely contemporary amplitude of 28,800 semi-oscillations per hour or 4 Hz ensures minimum long-term deviation. Another special chronograph feature greatly appreciated - not only by pilots under stress - is the important minute timer with its red tip, conspicuously placed at the center. This allows the user to easily keep track of stop functions up to 60 minutes and puts end to the irritating and distracting search for the usual small 30-minute timer. As a result of this important and useful function, the overall height of the chronograph is an impressive 14.5 mm. Further outstanding features of this chronograph movement are the 24-hour indicator at the "12" and the practical calendar with day and date. It goes without saying that apart from the time itself, all of the above indicators have to be easy to read, even when visibility is poor. With that aim in mind, the chronograph has sapphire crystal with inside anti-reflection treatment and a starkly contrasting dial. The luminous compound on hands and hour markers contains no tritium, so there is no radiation.

The distinctive design of this chronograph is timeless, as it is based purely on functional aspects. The solid stainless steel case with chamfered edges surrounds the chronograph movement like a safe. This mechanical microcosm remains unaffected by hard knocks, vibrations, and accelerations of up to 7 g in any direction and magnetic fields of up to 1000 oersted. The Military Chronograph is equally at home 200 meters under or 15,000 meters above sea level. The back is securely screwed to the case. The push button system and sapphire crystal have also been efficiently sealed. Finally, the recessed crown - which is seldom required thanks to the precise self-winding movement - is also carefully screwed to the case. There was of course another reason for choosing this method: it affords far greater protection against shocks.
