Georg Jensen Watch Koppel 32mm Quartz 3575701. The Koppel watch was revolutionary when it first debuted in 1978, the current generation continues this tradition and remains a masterclass in understatement. The minimalist, fluent lines of the case and hands have become a classic and the overall aesthetic is one of uncluttered purity. While beneath this sleek and organic exterior, the Swiss Made movement, delivers a high level of technical performance and excellence. Koppel is utterly singular, a story of balance and precision, both inside and out.
