Important facts
The Seiko Presage SSA445 is applied with a hardlex crystal, Seiko's proprietary glass technology. It is more scratch resistant than plexiglass and less expensive than sapphire, therefore a good choice for mid range wristwatches.
This watch has an automatic mechanical movement, which stores power in a mainspring, that is wound by an oscillating rotor while the watch is being worn. A mechanical watch movement is less accurate than a quartz one and requires regular servicing. It does not need a battery though and has a smoother sweeping seconds hand.
The case of this timepiece is made out of stainless steel which is a strong and durable material, therefore being resistant to scratches, dents, and general wear and tear. Steel is also highly resistant to corrosion and rust, but is also a hypoallergenic material, which means that it is less likely to cause skin irritation or allergic reactions. Let's not forget the versatility of steel, which makes this watch pair well with several different attires.
