This Sea-Gull Open Heart wristwatch pairs a 42mm round 316L stainless steel case with a synthetic sapphire crystal and a leather strap, giving it a refined look for business or casual wear. The open-heart dial reveals the automatic ST2504/ST2505 movement, which also drives a day-date calendar, while the push-button hidden clasp keeps the strap secure on the wrist.

With a 5 bar water resistance rating, it stands up to splashes and brief immersion, and the 1.65 in (42mm) case sits comfortably on a range of wrist sizes. The watch is powered by automatic winding and comes with a 1-year warranty.
