Nivada-Grenchen Clamshell Case Diver Chronograph – Landeron Cal. 48


Out of stock

Professionally restored and fully serviced in-house here at the Localtime Spa, the so called “Clamshell” case was patented by Nivada and used on some of their waterproof watches. Clamshell cases are made in a way that, the top of the case is an one-piece gold-plated ‘receiver’ that takes the rest of the watch which comprises of a ‘shut’ stainless steel caseback as an one piece with the movement, dial, crystal, etc. This is then screwed in with 4 individual screws, one on each lug. The movement is a Landeron Cal. 48. The case has been beautifully re-plated with yellow gold and the dial lightly cleaned. The watch comes on a brown leather strap with two more NATO’s, a Bond canvas and a camel brown leather one, both with gold-plated metalware to match the watch case. More information on the great quality leather NATOs can be seen in our eBay store, under eBay item number 200973049058. We have made many photos of the watch and also included some snapshots from the restoration. As with all the watches we restore in-house here at the Localtime Spa, this one too will arrive to you with a 6-month written warrantee. Please feel free to ask us whatever clarification you might need.
