Omega Constellation 34mm Meister Signed Pie Pan Dial Watch

Q: What does the Meister signature on the dial mean?
A: Meister is a historic Zurich-based jeweller and authorised retailer. In the 1960s, Omega supplied some watches with the retailer’s name printed on the dial. This double-signature adds provenance and is sought after by collectors.

Q: What is a pie-pan dial and why is it special on the Constellation?
A: The pie-pan dial has a raised centre with sloping, faceted outer sections that resemble an inverted pie tin. It became an iconic design of mid-century Constellation models for both its distinctive look and legibility.

Q: Which movement does reference 168.005 use, and does it have a quick‑set date?
A: This reference was delivered with chronometer‑rated automatic calibres 561 or 564, depending on the production year. Calibre 561 does not have a true quick‑set date; calibre 564 features a pull‑push quick‑set mechanism. As this listing does not specify the calibre, please contact us if you’d like us to confirm the exact movement in this example.

Q: How should I set the date safely on these movements?
A: For non‑quick‑set (cal. 561), advance the hands past midnight to change the date, or use the back‑and‑forth method (around 9 pm to midnight) repeatedly until the correct date is shown. For quick‑set (cal. 564), pull the crown to the second position and push in to advance the date one day at a time. Avoid using the quick‑set between about 10 pm and 2 am to prevent strain on the mechanism.

Q: Is this vintage Constellation water‑resistant for daily use or swimming?
A: The original rating for this era was 3 bar/30 m, but given the watch’s age we do not recommend submerging it or exposing it to showers or swimming. Light splashes during careful handwashing are generally fine, but moisture should be avoided and gaskets should be checked during service.

Q: How does the 34 mm case wear, and what wrist size will it fit?
A: The 34 mm case wears elegantly thanks to its sculpted lugs and slim profile. On its current bracelet, this watch fits up to approximately a 17.5 cm wrist (as listed). The lug width is 18 mm, so most 18 mm straps will fit if you’d like to change the look.

Q: Can the beads‑of‑rice bracelet be resized or swapped for a strap?
A: Yes. The bracelet can usually be resized via removable links and clasp micro‑adjustments. If you prefer a different fit or style, the 18 mm lug width makes it easy to fit leather, suede or other straps. If you need extra links, please contact us and we’ll advise on availability.

Q: What does the observatory medallion on the case back represent?
A: The observatory with eight stars celebrates Omega’s chronometer records and first‑place awards at historic observatory trials in the mid‑20th century. It is a hallmark of the Constellation line and symbolises precision.

Q: How often should a vintage Omega be serviced, and what do you check?
A: Omega recommends a complete service about every 5–8 years, depending on use and environment. For vintage pieces, we suggest a check‑up sooner if accuracy changes or if you plan frequent wear. Our team verifies function and timekeeping prior to sale; water resistance is not guaranteed on vintage watches and should be tested after any service.

Q: What is included with this watch?
A: Everything that comes with the piece is listed under the product information on this page. If items such as a box or papers are not mentioned there, they are not included. We are happy to clarify what is present with this specific watch before purchase.
