Orbita's Siena 3 Programmable Watch Winder, shown here in Burl, available in Teak, has a sloped front case design which affords perfect visibility of your timepieces. The top is fitted with a beveled glass viewing panel and superb quadrant hinges. The interior surfaces are lined in rich suede. The Siena 3 utilizes Orbita's "made-in-the-USA" patented Programmable Winding Movement, a sophisticated microprocessor control with four winding cycles of 650, 800, 950 or 1300 Turns Per Day (TPD). You may choose clockwise, counter-clockwise or automatic reversing rotation. The iron-less core, Swiss-designed motor operates on 6VDC battery power using Alkaline C cell batteries (A "low voltage" battery light automatically signals when battery replacement is due). Multiple layers of high gloss polyester lacquer enrich the Teak finished case . The bottom surface of the case is covered in suede to prevent damage to your fine furniture finish.
