Arsa, also known as Auguste Reymond, is a Swiss watch manufacturer founded in 1898. In 1906, Arsa bought the Val de Joux Watch Co, which became Valjoux after being sold. They also acquired Unitas in 1926. Arsa was part of the ASUAG group, which later became the Swatch Group. The watch you see here has a distinct Felsa 690 Bidynator automatic movement, one of the first calibers with bidirectional rotor winding, introduced in 1942. It also comes with a custom leather NATO by Joe from Diaboliq Straps – a skilled artisan known for his military-inspired straps. **Condition:** Very good for its age. Minor markings on the case and crystal. Please see the pictures for a better description. Comes with a handmade leather NATO. **Case Size:** 33.7 x 41.8mm gold-plated case with a thickness of 11.5mm and a lug width of 18mm. **Crystal:** Acrylic. **Movement:** Felsa 690 Bidynator, 17 jewels, 18,000 bph with a power reserve of 44 hours.

Payment methods include Wise, ACH transfer, Revolut, Bitcoin (On-Chain or Lightning), or PayPal G&S for buyers with solid references. Add +6% for currency conversion fees on the latter.

Lange was founded in 1845 by Ferdinand Adolph Lange in the town of Glashütte, near Dresden, in the state of Saxony. Under Ferdinand, and then, following his death, his sons Emil and Richard, Lange produced quality pocket watches, the company's very best products generally being given the "1A" designation. Under subsequent generations of the Lange family, the company continued to produce pocket watches and, like many German watch makers, produced oversized wrist watches for use by German airmen in World War II.

In 1948, the post-war Soviet administration expropriated the company's property, and the Lange brand ceased to exist. However, in December 1990, following German reunification, the founder's great-grandson Walter Lange, together with watch industry executive Günter Blümlein, restored the company with the assistance of several Swiss watch manufacturers, including IWC and Jaeger-LeCoultre. The refounded Lange, again operating from Glashütte, presented its first range of wrist watches in 1994. Today, A. Lange & Söhne (litt. A. Lange & Sons) wrist watches are sold globally and Lange, like IWC, is a member of the Richemont group.
