Oris Watch Commissions Biggest Outdoor Watch Ad

Oris is promoting its Aquis Depth Gauge with the largest ever outdoor watch advertisement, measuring 1,944 square metres.

The ad is made up of two huge billboards, each measuring 81 metres high and 12 metres wide.

The billboards appear on the side of a building in Bangkok, Thailand. The central location means it will be seen by over 90,000 drivers per day, and is expected to reach 16 million people in its six-month lifespan.

The Oris Aquis Depth Gauge is the first divers watch to measure depth by allowing water to enter the timepiece. It has a special sapphire crystal that is 50% thicker than an average top glass, with a channel milled into the side. The channel runs anticlockwise around the dial and stops between 1 o'clock and 2 o'clock, with a hole at 12 o'clock.

As the wearer descends under water, the air inside the channel is compressed by the surrounding water pressure, allowing water to enter the channel through the hole. A grey indication around the outside of the dial differentiates between water and compressed air, so the diver's depth can be read using a yellow depth scale.

The Aquis Depth Gauge has a 46 mm stainless steel case, and a unidirectional revolving top ring with black ceramic inlay and minute scale. It is water resistant to 500 metres and powered by the automatic Oris movement 733.
