The case of the SNA113 measures approximately 40mm wide (not including the crown) by 10mm 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 19mm and the bracelet band can be adjusted to fit using a link removal tool or removed using a band removal tool to be replaced with another band.
Transform the look of this watch by adding a 19mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.
The SNA113 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.
