A multifunction watch has three sub-dials; one sub-dial displays time in 24-hour format, while the other two display day and date.

The crown works in 3 positions the leftmost position is where the watch functions normally, the center position can be used to adjust the day date while the pulled-out extreme right position can be used to adjust the time. The 24-hour time format dial is synchronized with time in the watch and doesn't need separate adjustments.

Ion plating is a vacuum plating technique where metal is transferred on the surface, it's at least 50 times stronger than wet plating (where the metal is transferred via ionized liquid). In other words, the Ion plated surface has stronger resistance to water, sweat.

This results in a lot longer life of crowns to both wear and tear corrosion.

This is needed to provide extra resistance to sweat which is acidic and hence highly corrosive.

Usually, a battery will last for over 12 to 18 months.

The VX3J movement used in this case has a life of 15-20 years, over this time period the watch will display time with very high accuracy.

The watch strap is made of genuine leather both on top and bottom. The leather on the bottom has special treatment which results in extra resistance to water sweat. Usually, the watch straps are PU on top while genuine leather is only used in the bottom. Each TZARO watch comes with all Genuine Leather strap which has a long life.

The water resistance comes from the crown which needs to have a washer and needs to perfectly fit in, the glass needs to be strong enough to handle the pressure and needs to be backed by a washer, and the case back needs to be airtight. Every TZARO watch is 30 meters waterproof and has been tested in pressure chambers for being waterproof.

Ring set case has a ring that has been attached to the case, this allows differential plating to the case (where we can plate the case in one color and the ring in some other color).
