Description
Pre-owned. Boxes have deteriorated and thrown away but comes with the original manual and warranty card in docket.
This is a very rare IWC Portofino Moonphase made together with Sincere Haute Horlogerie (SHH) in 2008 with just twenty pieces produced. It is un-numbered but serialised and online literature is unfortunately non-existent by now. This is a single owner’s watch who purchased it from Sincere Haute Horology boutique at Hilton, Singapore.
Watch is in near mint condition & not polished so do expect micro hairlines on the polished gold case and they can be easily removed upon request. This is a large watch but very slim and modelled after the famous Ref.5251 which was produced only in yellow gold. Functions checked and in good working order.
The moon phase display on this watch is so accurate that it only deviates by one day in 122 years from progress. It is fitted with the pocket watch derived Calibre 98800 movement with an oversized regulator. The back glass is etched with Sincere logo and “SHH 2008 One of 20”.
SHH was a boutique store dedicated to high horology timepieces started by Sincere Watch Ltd based from Singapore. Each year, SHH collaborates with a some of the leading names in watchmaking to create limited editions to be sold exclusively through SHH boutiques.
A collector’s item. The original boxes & paper have been found but as we all know the material of these boxes always melt away and becomes a mess so it has been discarded but the documents and warranty card (More important) accompanies with this sale.
