Scent Profile Compared

Tom Ford Oud Wood opens with a burst of exotic rosewood, cardamom, and a whisper of Sichuan pepper. The heart reveals creamy sandalwood, vetiver, and a smooth, smoky agarwood (oud) that is never harsh. The dry-down settles into a warm, slightly sweet amber, tonka bean, and a touch of vanilla. It’s woody, leathery, and resinous - a sophisticated, unisex scent that feels luxurious.

Calvin Klein Eternity starts with fresh lavender, mandarin, and green notes like freesia and sage. The heart is a classic floral bouquet: lily, jasmine, rose, and carnation, underpinned by a soft herbal touch. The base is clean and mild with sandalwood, musk, and amber. It’s a light, airy, powdery floral - more traditional and feminine-leaning, but wearable by anyone who likes a vintage-inspired soap scent.

Where Oud Wood is dark, rich, and complex, Eternity is bright, simple, and clean. Oud Wood feels like a leather-jacket evening, Eternity like a crisp white shirt and sunshine.

Longevity and Sillage

Tom Ford Oud Wood lasts 7-9 hours on skin with moderate projection. It clings close for the first hour, then releases gentle waves of smoky wood. On clothes, it can last 24+ hours. Sillage is moderate - it’s noticeable but not overwhelming, perfect for intimate settings.

Calvin Klein Eternity lasts 4-6 hours on skin with soft to moderate projection. It fades quickly from the opening to a skin scent within two hours. On clothes, it lingers about 8 hours. Sillage is close - you won’t fill a room, but those near you will catch the floral sweetness. Eternity is a low-key scent that won’t offend.

If you want a scent that lasts through dinner and into the night, Oud Wood is the better choice. Eternity needs reapplication for evening events.
