The case of the SNA057 measures approximately 39mm wide (not including the crown) by 12mm thick and is water resistant to 100 meters. This should be sufficient for splashes, rain, baths, showers & swimming (shallow diving) but is not recommended for scuba diving. The crown does not screw down which increases the risk that it could be pulled out accidentally while under water. The titanium bezel is fixed (cannot be rotated). The gap between the lugs is 20mm and the bracelet band can be adjusted to fit using a link removal tool but may be difficult to replace with another band due to the shape of the lugs.
The SNA057 provides the following features and complications:
- Second hand
- Seconds subdial
- Minute hand
- Hour hand
- Alarm subdial
- Dual time subdial
- Chronograph that includes a subdial for minutes with a minimum resolution of 1/5 second and a maximum duration of 60 minutes. The central second hand is used by the chronograph. When the chronograph is not in use this hand is stationary. Seconds are shown on the seconds subdial.
- Date window to show the day of the month. Note that some watches may be damaged if you attempt to change the date between 8:00 PM and 2:00 AM, in which case you should change the time to be outside that range first then reset the time after adjusting the date. Check your watch manual for details.
