Stainless steel 316L (Stainless Steel) is a very durable material that theoretically can not be destroyed. It is hard (non-bendable and non-crackable), color stable, antiallergic (does not react with body fluids and therefore no metal components are not released into the skin and flesh) and has anticorrosive surface (the surface is resistant to oxidation and corrosion. Moreover, it is also resistant to fresh and salt water).

Mostly of rubber, resins or silicone. This type of material has high flexibility, is hypoallergenic, water resistant, and does not absorb sweat.

The watch is powered by a battery.

Part of the watch is an alarm clock that can be set at different times. When activated, the alarm sounds.

EL panel illuminates the dial and thus ensures easier readability. The illumination is activated by a touch of a button.

The watch calculates calories consumption during exercise.

The adaptive and personalized Polar STAR Training Program helps you reach your training targets. The Training Program gives you the optimal intensity, calorie, and time targets for your training and allows you to decide what kind of exercise you want to do and when. Polar STAR Training Program is based on your personal information (weight, height, age, sex), fitness level, activity level, and training goal. Your training computer gives feedback on your performance after each training session and once a week. By analyzing your weekly training results and changing fitness level, the training computer adapts to your training habits and gives you training guidance for the following week.

Part of the watch is a chest strap to monitor heart activity.

The fitness program incorporated in this model helps optimize your strength development. At polarpersonaltrainer.com you can schedule up to 3 different series of fitness exercises and then download them to your FT80. In the actual exercise the device itself suggests rest periods between series and warns when pauses ends. When you do not have too much experience with body building, this program is exactly what you are looking for.

The display shows the current date. It is pre-programmed, so there is no need to set short and long month and leap years. Most watches have this pre-programmed date until 2099th.

Stopwatch enables to measure time intervals.

The Polar Fitness Test resulting an OwnIndex is developed to measure aerobic (cardiovascular) fitness. It predicts maximal aerobic power (maximal oxygen uptake, VO2max in ml.min-1.kg-1). This indicates how many millilitres of oxygen your body is able to transport and use per each kilogram of your body weight in one minute. The test is targeted to healthy adults. It is fully automatic and can be performed at rest in less than five minutes. No other equipment such as treadmill is needed. It is an easy, safe and quick way to estimate your maximal aerobic power. It is as reliable as any other submaximal fitness test.  The Polar Fitness Test is based on: Resting heart rate, Heart rate variability, Gender, Age, Height, Body weight, Self-assessment of the level of long-term physical activity (last 6 months).

The self test to diagnose relaxation rate of recovery of the body after previous load and thus helps further planning of the training process.

Watches marked with water tightness 50M/5ATM are designed for incidental contact with water (car wash, rain), but also for surface swimming without diving. 50M/5ATM indicates the degree of water resistance standardized by ISO 2281. ISO tests include temperature changes, depth, pressure (water and air) for different times under rest and during manipulation with the operative part of the watch.
