Own the Moon and the Stars A deep blue aventurine dial. A graceful moonphase. A 38 mm case made to sit beautifully on every wrist. The Atlantic Worldmaster 1888 Automatic Moonphase Aventurine carries a rare kind of elegance. Soft sparkle, classic Swiss watchmaking and a refined presence that works on leather or steel. For women. For men. For anyone drawn to time with a little romance. A Little Magic in Every Phase. There are watches you wear because they match your day. And then there are watches you choose because they pull you in. The Atlantic Worldmaster 1888 Automatic Moonphase Aventurine has that kind of attraction. Its deep blue aventurine dial catches the light with a soft, almost secret sparkle, while the moonphase brings a touch of old-world romance to the wrist. It is elegant without trying too hard. Refined without feeling distant. At 38 mm, it has the kind of size that works beautifully on women and men, slipping easily from summer linen to evening wear, from a dinner by the water to a long day in the city. On the blue leather strap, it becomes expressive, warm and slightly poetic. On the stainless steel bracelet, it takes on a polished, classic character made for everyday elegance. A Swiss Made automatic watch for anyone drawn to beauty, rhythm and the small details that make time feel personal.
