Using your Shinola Canfield 43mm Chronograph is easy. The screw - down crown ensures a tight seal and you can operate the chronograph functions as you need. When wearing it, it's suitable for various occasions. For the office, it adds a touch of sophistication, and for sports like on the racetrack, it can keep accurate time. As for maintenance, keep it away from extreme temperatures and strong magnetic fields. Wipe it gently with a soft cloth regularly to keep it clean. If you plan to swim or be in water, note that it has a 5 ATM depth rating, but don't expose it to high - pressure water. Also, if you want to engrave something on the case back plate, it's available, but make sure to have it done by a professional to avoid damaging the watch.
