DETAILED DESCRIPTION

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: automatic 6R35

6R35 is an automatically retractable movement that is part of the high-performance Seiko 6R series. The calibre introduced in 2019 mainly differs from its 6R15 predecessor due to a significant increase in the power reserve, which reaches up to 70 hours.

LumiBrite

LumiBrite is a dramatically improved fluorescent luminous paint that quickly absorbs a greater amount of the light energy exposed to it and glows brighter and much longer in the dark. As its name suggests, LumiBrite starts glowing brightly in the dark and fades slowly. It is also completely free of radioactivity, ensuring safety for people and the environment. It is the ideal successor to both radioactive luminous paint and conventional fluorescent paints.

Water resistance: 200M/20ATM

Watches marked with water tightness 200M/20ATM are designed for swimming, snorkeling, and for diving with breathing apparatus. 200M/20ATM 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: Folding clasp

A Folding clasp is the most widespread method of fastening watch straps and wristbands. It's a simple and reliable fastening method. If it accidentally unfastens, it won't unfasten completely, and the watch will remain on your wrist.

Bracelet 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). 



i replaced the bracelet in a watchmaker with a very beautiful Angus-J Louis Jubilee bracelet and resize it to fit my wrist.Please check pictures
