Sell your IWC in Switzerland

An IWC is best sold in Switzerland through a buyer who collects bids from several dealers and passes on the highest one as a binding offer. Reference, calibre family, metal, completeness with box and warranty card and the overall condition decide the sum. Portugieser and Big Pilot are the most wanted lines from the Schaffhausen manufacture.

Uhrenkontor is a purchasing platform run by Solidas GmbH, registered in the canton of Schwyz with its office in Schindellegi SZ. Over 25 partner dealers across Switzerland assess every IWC submitted, working from watch data and photographs. The best bid reaches you as a binding offer within 12 hours on working days; it is free, without obligation and valid for several days. Watches from around CHF 3,000 market value upwards are bought, and dealers never receive your contact details.

What determines the value of an IWC?

Reference and calibre family

An IWC reference begins with IW and four digits for the model, followed by two digits for the execution, IW358304 for the Portugieser Automatic 40 for example. The calibre family drives the assessment: the 52000 calibres with their twin barrels give seven days of power reserve, the 69000 calibres are column-wheel chronograph movements, and the 82000 calibres are automatics with Pellaton winding and 60 hours of reserve. Older models built on supplied base movements are valued differently from in-house calibres.

Box, warranty card and invoice

A full set comprises the watch, the original box, the warranty card with serial number, the booklets and any additional straps. IWC registers watches through My IWC and grants an extended warranty after registration, which helps at the point of sale. Watches without papers are bought; the check of serial number and movement is simply more thorough.

Condition and servicing

IWC recommends a service roughly every five to seven years. Dealers assess case, crystal, strap and clasp, together with the function of a chronograph or power reserve indicator. Unpolished cases are preferred. IWC service records tell in your favour, though servicing before a sale is rarely economical.

Demand for the model and configuration

The Portugieser Chronograph, the Portugieser Automatic and the Big Pilot are the quickest to place, followed by the pilot's watches and the Ingenieur relaunched in 2023. The Portofino and the Aquatimer have a smaller following; with small or quartz steel models the market value can sit below the purchase threshold.

Which IWC models are most in demand?

The Portugieser has been the classical line since the 1930s, with Arabic numerals and a railway minute track. The Portugieser Chronograph IW3716 with the in-house calibre 69355, the Portugieser Automatic 40 (IW3583, calibre 82200) and the Portugieser Automatic 42 (IW5007, calibre 52010 with seven days of power reserve) are the most searched-for references. Perpetual calendars and the Yacht Club are assessed by specialist dealers.

The Big Pilot, with its large conical crown, is the best-known pilot's watch of the brand. The 46 mm IW5010 with power reserve indicator, the Big Pilot 43 introduced in 2021 (IW3293, calibre 82100) and limited editions such as Le Petit Prince are in demand.

The other pilot's watches cover the Mark series, currently the Mark XX (IW3282, calibre 32111), the Pilot's Watch Chronograph 41 (IW3881, calibre 69385) and the Top Gun models in ceramic or Ceratanium. Earlier Mark XV, XVI and XVIII references are bought as well.

The Ingenieur was relaunched in 2023 as the Ingenieur Automatic 40 (IW3289, calibre 32111) with an integrated bracelet, picking up the thread of the Ingenieur SL of 1976. Both the new generation and older references with a soft-iron inner case are assessed.

The Portofino is the plain, round dress watch, for instance the Portofino Automatic IW3565 or the Portofino Chronograph. The Aquatimer is the diver of the house with an internal rotating bezel, such as the Aquatimer Automatic IW3290.

How selling your IWC works

1. Fill in the form: reference, year, condition and what is included, with at least three photographs. It takes about three minutes.
2. Receive your offer: over 25 partner dealers assess the watch; the highest bid reaches you as a binding offer within 12 hours on working days and stays valid for several days.
3. Hand the watch over in person: anywhere in Switzerland and Liechtenstein, at a bank branch, a notary's office, your workplace or your home. Condition, authenticity and completeness are checked there; if anything differs from the description, an adjusted offer follows at no cost.
4. Payment: in cash, by bank transfer or by Twint.

How to recognise a reputable buyer

A reputable buyer names a figure, not a range. Only a stated sum with a validity period can be compared with other offers, whether from an authorised dealer, an online platform or an auction house.

The company behind the offer can be checked. Uhrenkontor is operated by Solidas GmbH, entered in the commercial register of the canton of Schwyz. Legal form, domicile and authorised signatories are visible in the Swiss company index Zefix.

Discretion is a given. At Uhrenkontor dealers see watch data and photographs only, never your contact details. There is no shop; the handover takes place where you choose.

A reputable buyer applies no time pressure. Several days of validity leave room for comparison. There is more on this in the guide to selling a watch in Switzerland and on How it works.
