Rarely offered for sale – Sinn 356 UTC / GMT Flieger

This specific model has been discontinued for some years now and is not easy to find.

The watch offered for sale received a full service at Sinn headquarters in Frankfurt in summer 2021
(Invoice from € 440 / US$480 available)

Dark green Barton leather strap with original 20mm Sinn buckle included (strap is hardly used and very smooth).
Dial is black, Arabic numbers and hands with luminova

Watch is in excellent condition, with very little marks here and there from usage, most specific ones:

• Bezel has slight marks between 4 and 5
• Case (marked “SUG” between the lugs at 6) has minor marks on the non-crown side
• Acrylic has two very little bumps at 5 (recently polished with polywatch, so no swirls or anything)
• Lugs on underside have minor marks from straps changing

Tried to photograph everything, but it is hard to capture the little blemishes.
All photos are taken with an iPhone 13 pro and unfiltered or adjusted.

With the pretty recent service, all chronograph and time functions work as they should.
I do not know the time difference since I am unable to measure that.

Very versatile and cool looking watch.

UTC hand can be hidden under the hour hand (and then runs synchronously with the hour hand) if you just feel like no UTC is needed at a given moment.

No BOX nor papers – but copy of invoice from Sinn Frankfurt (anonymized) will be provided.
Watch will come in a Sinn travel case.

Asking price: US$ 2700 net
Domestic shipping CONUS included – fully insured (shipped form a USA address)

If requested I can ship worldwide, fully insured. In that case I will either ship from USA or from the Netherlands.
