BULOVA PRECISIONIST 98B358

Case material: stainless steel

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).

Movement: battery

The watch is powered by a battery.

Strap material: plastic

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

Date – the day of the month

Displays the current day of the month period from 1 to 31 December.

Stopwatch 1/1 seconds – 12 hoursMeasurement accuracy of 1 second. The maximum measured time is 12 hours.

High-frequency technology

Movements from the Bulova Precisionist series feature UHF oscillator (Ultra High Frequency) with up to 262 kHz up to eight times the usual quartz gauge. The benefits of high-frequency technology include better clock accuracy and smoother operation of the second hand.

Water resistance: 300M/30ATM

Watches marked with water tightness 300M/30ATM are designed for swimming, snorkeling, and for professional diving with breathing apparatus. 300M/30ATM indicates the degree of water resistance standardized by ISO 6425. 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. The dive models, subsequently performs the test of resistance to salt water and the ability to cope with the watch positive pressure (decompression simulation).

Crystal: sapphire

Sapphire glass in the watch was made in a laboratory by melting aluminium oxide (Al2O3) in the presence of hydrogen and oxygen at 2000 °C. After crystallisation into the corundum ‘pear’, it’s cut and further processed into the desired shape and size. Sapphire glass is the hardest glass used in watches. It would be second behind diamond on the scale of mineral hardness, so it can only scratched by diamond. Its only disadvantage is its fragility.

Closure type: pin buckle

The most widely used method of fastening, which is mainly used in leather and silicone straps. Simply turn on the buckle into the required holes as needed.
