Jeremy Dunham of Compass has closed the sale of Penthouse PH-402 at Watchcase, 15 Church Street in Sag Harbor Village, for $7,300,000. The home closed in September 2026.

The penthouse sits high above the village inside the historic Watchcase Factory, the brick landmark turned into one of the Hamptons' most coveted condominium addresses. Spread across about 1,937 square feet on two levels, the three-bedroom home pairs the building's original exposed brick, arched windows and timber beams with crisp modern finishes and sweeping views over Sag Harbor and the water.

The entry level opens into a dramatic great room where the kitchen, dining and living areas flow together around a fireplace beneath beamed ceilings, with tall black-framed windows on three sides. The kitchen pairs warm wood cabinetry with stone counters, a farmhouse sink, a professional range and a wine refrigerator. A powder room completes the floor.

One flight down, the private bedroom level holds two guest bedrooms sharing a full bath, a waterfront-facing balcony and an en-suite primary suite designed as a quiet retreat.

The crown of the home is its private rooftop terrace, set far above the village with water views, lounge and dining areas, a gas fire pit, a full outdoor kitchen and its own powder room: an outdoor living room for long summer evenings under the Sag Harbor sky.

Watchcase residents enjoy concierge service and porters, a fitness center with locker rooms, a yoga studio, a spa treatment room and sauna, a heated 64-by-22-foot saltwater pool, a live-in resident manager and a full-time superintendent, all steps from Main Street and the harbor.

For Dunham, it is a marquee village close: a true penthouse in Sag Harbor's signature building.
