The Grönefeld brothers, independent Dutch watchmakers, are renowned for their distinctive designs and impeccable finishing. The 1941 Principia Automatic exudes class with presence. This variant's matte light blue, multi-layered, solid sterling silver dial creates a striking contrast against the flame-blued hands with mirror-polished centers and is one of the most captivating executions of the model. The jaw-dropping, hand-finished automatic Calibre G-06 movement resembles the facades of Dutch houses and features stainless steel bridges hand-bevelled for up to 10 hours each, a uni-directional 22k gold oscillating rotor spinning on lubrication-free ceramic ball bearings, and 31 jewels, many of which are set in solid gold chatons. Because the brothers take such a painstaking approach to finishing, production is naturally incredibly limited. This purist-acclaimed timepiece, with its comfortable, beautifully sculpted 39.5mm case with removable lugs, would make a standout addition to any collection. •Guaranteed to be 100% authentic. •Comes with the impressive Gronefeld boxes, papers (dated 11/7/2024), three blue Gronefeld straps, one custom brown leather strap, and two strap holder pouches as shown. •All functions are operating as intended. The watch is running well. •••COSMETIC CONDITION••• Overall: Good, pre-owned condition. It is absolutely stunning on the wrist! The watch presents very well on the wrist and shows ordinary surface wear and some small nicks upon inspection. If desired, a professional polish could restore the watch to practically mint condition, though we would not consider it worthwhile at this time, as the wear is not very apparent when the watch is worn. The crystal is clean. The leather straps are in excellent condition showing little to no signs of use. It would be my pleasure to answer any additional questions you may have. A secure, reliable, transparent transaction is a top priority. Luxury timepiece trade-ins are welcomed! Located in Miami, FL.
