1960’s HELBROS [Swiss] Ref. 14510 Vintage Chronograph Watch – Valjoux Cal. 7730


1 in stock

Professionally restored and fully serviced in-house here at the Localtime Spa, a HELBROS Ref. 14510 chronograph with a LeJour marked Valjoux Cal. 7730 movement and case [large 36.25mm case, 38.25mm counting the crown at 3h], from the late 1960’s.

These were made by YEMA [France] for many brands in the USA and we also see some of them with Yema-branded movements/cases. Beautiful silver dial with applied silver indices and stunning ‘alpha-typex’ hands. We have included many photos, including some macro closeup snapshots we took, just for fun, as well as, some snapshots from the service bench. This lovely chronograph is fitted with a handmade premium calf leather strap in tan, custom made for Localtime in Italy [more information and variations can be seen in our eBay store, under eBay item number 401105271426].

As with all the watches we service here at Localtime, this too comes with a written 6-month written warrantee from the date of purchase. Feel free to contact us for whatever questions you might have.

Information about the Localtime straps: Handmade from premium calf leather to our specifications in Italy they come in 5 sizes [lug width/buckle width]: 18/16, 19/16, 20/16, 21/18 and 22/18mm & 4 colours: tan, brown, dark brown and black. We sell these separately in our eBay store under eBay item number 401105271426 and you can also see them in the last photo here.
