Zinniker Uhren & Schmuck

Zinniker Uhren & Schmuck sits on the Marktgasse in Bülach's old town, under 10 minutes' drive from Zurich Airport and an easy stop off the S-Bahn line into the city. It is a small, owner-run shop rather than a chain outlet. Johannes Maag, a state-certified master watchmaker (Eidg. dipl. Uhrmachermeister), has owned it since 1992: he signed the purchase contract on 23 May that year, 12 years after finishing his own apprenticeship at what a 2022 Tages-Anzeiger profile called the shop's original "Traditionsgeschäft." That kind of continuity is worth something to a buyer new to the region. A lot of jewellery sellers with a Zürich-area web presence are recent or online-only; this one has been under the same owner, in the same building, for over three decades, and the shop marked that 30-year milestone in 2022 with a storewide discount and a customer competition.

What's actually on the shelves

The watch side of the online shop is organised by five brands: Certina, Ebel, Frederique Constant, Porsche Design and Rado. That is only part of the picture at the physical counter, though: both Omega's and Longines' own official dealer locators list Zinniker as an authorized point of sale and service in Bülach, brands that do not have their own tab on the website. Worth a direct question if you have a specific Swiss brand in mind rather than assuming the online catalogue is the full range.

Jewellery is grouped by maker rather than by piece type: Cammilli, Furrer Jacot, Gellner, Leo Wittwer, and the shop's own line, sold as Eigenkreationen ZINNIKER. Prices across those lines vary a lot. A Gellner ring set with a pink Ming pearl on a black-ionised band lists at CHF 1'435, while a Cammilli necklace at the top of the range runs to CHF 12'140, with most rings and colliers priced somewhere in between. Furrer Jacot, a Swiss brand that specialises in wedding rings, supplies the shop's bridal pairs: one matched set on the site, reference 71-82230, in 750 white gold, prices at CHF 4'940 for the woman's ring and CHF 4'690 for the man's.

A goldsmith on the premises, not just behind a sales counter

The shop's own listing on the Swiss directory search.ch describes creative individual pieces being made "in der hauseigenen Goldschmiede," including to a customer's own wishes, and lists jewellery alterations, engraving, restoration and refinishing among its services alongside a watchmaker's workshop. That matches the team page on the shop's own site, which names Marco Capeder specifically as goldsmith, jewel-setter and jewellery designer, working alongside Mikael Hake as watch repair technician and three sales advisors under Maag. Having a goldsmith and a watchmaker on the payroll, rather than sending work out, is what lets a shop like this resize a ring or fix a scratched watch case without a courier trip in either direction, and it is the basis for the "Eigenkreationen" line: pieces designed and made on site rather than bought in from a supplier's catalogue.

Where it falls short of a dedicated bridal counter

Here is the honest gap for this tenant's angle. Nowhere on zinniker-ag.ch does the word "Trauring" or "Verlobungsring" appear; a search of the site itself turns up nothing under either term. The only explicitly bridal products are the Furrer Jacot Eheringe (wedding bands), sold as individual products rather than gathered under their own category tab, mixed in with rings and necklaces from the other jewellery brands. There is no page, product, or category framed specifically around engagement rings. In practice that means a reader looking for an engagement ring here would most likely end up commissioning one through the in-house goldsmith rather than choosing from a labelled shelf of solitaires, since the published catalogue simply does not include that as its own line. It is a real gap next to a dedicated bridal specialist, and worth knowing before you make the trip out to Bülach expecting a display case of engagement rings specifically.

What a newcomer to Zurich needs to know

The site itself is German only; there is no English version of any page. That said, the shop's local.ch business listing gives English, French and Italian as additional languages spoken at the counter alongside German, and separately lists EUR as an accepted currency next to the standard Swiss card and cash options, useful if you are paying before you have opened a Swiss bank account or exchanged all your cash. Neither the shop's own site nor its directory listings publish anything about shipping, customs duty, or how long a commissioned piece or a resize takes to complete. If any of that matters for your situation, whether you are ordering before a move or need a ring resized once you have settled, it is a question for a phone call to 044 860 12 23 or an email to info@zinniker-ag.ch rather than something posted online, so plan for that conversation before you commit to a date. There is also no documented online booking system for a private consultation on the shop's own site, so calling ahead to arrange a time is the practical route rather than assuming you can walk in and get someone's full attention.

Opening hours are published on the contact page: Tuesday to Friday from 9:00 to 12:30 and 13:30 to 18:30, Saturday from 9:00 to 16:00, and closed Monday. The Altstadt location is compact and largely pedestrian, with parking and a public transport stop nearby according to the shop's local.ch listing, so a short visit works whether you drive in from the airport corridor or take the train from central Zürich.

Track record

Beyond the 30-year figure and the 1992 ownership date, the shop shows up consistently in local press: a 2021 feature in the Zürcher Unterländer covered its goldsmith and watchmaking work, and a Fokus Swiss piece the same year profiled Maag and his team directly. Reviews on local.ch put it at 4.7 out of 5 from 11 ratings, with comments citing consistent service over repeat visits. It is also demonstrably still trading day to day rather than coasting on an old web presence: as recently as late summer 2024 it ran a storewide sale of up to 60 percent off selected watches and jewellery, and its commercial registry listing shows an active status.

Who it suits, and the verdict

This is a solid pick for someone who wants an actual goldsmith relationship rather than a transaction: a resize, an engraving, or a custom piece built from scratch, backed by a shop that has been run by the same watchmaker for over 30 years and is still an authorized Omega and Longines service point. It is less suited to someone who wants to walk into a dedicated engagement-ring boutique and pick from a case of solitaires, since that specific framing simply is not what the site or the shop's own product pages offer; what is confirmed is wedding-band work through Furrer Jacot and custom goldsmith commissions. The German-only site and the absence of any published shipping or turnaround information are minor friction for an expat buyer, easily solved with a phone call, and neither should be read as a reason to skip a shop with this much sourcing and service depth on the ground in the Glattal and Unterland area.
