The watches come in four model ranges and feature many strap and dial options along with 39mm wide and 36mm steel case sizes (with 60 and 50 sprays accordingly in each). You can visit their site to see the many different styles available. The Perfume Watches comes with a little filling kit complete with a funnel, vial, and pipette to load the watch with your favorite perfume. To spray the perfume you need to twist away the shield over the atomizer at 2 o'clock and press down on the pusher.
