Replica volume for Glashütte Original is low. The realistic risks are redialled examples and confusion with the many other Senator chronograph configurations.
Known issues in the market
- The Senator Chronograph Panorama Date exists in steel, red gold and platinum with several dial options. Reference numbers differ across all of them, so match the reference rather than the description.
- Panorama Date is the house signature and the hardest detail to imitate convincingly, because both date discs sit on a single plane with no dividing bar between them.
- Service dials and relumed markers turn up on watches that have been through non-authorised repair. Printing quality is where that usually shows.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| dial | Panorama Date window | Two white numerals on black, level with each other, with no bar or step between the discs. It reads as a single window | A visible divider, a step in height between the digits, or numerals of different sizes |
| dial | Numerals and lume | Details printed in white on a fine matt varnish black dial, Roman numerals at 6 and 12, with Super-LumiNova partially inlaid into the markers, numerals and the hour, minute and stop-second hands | Glossy dial surface, numerals at every hour, or lume applied on top of the printing rather than inlaid |
| movement | Calibre 37-01 through the sapphire back | Glashütte three-quarter plate with stripe finish, skeletonised rotor carrying the double-G symbol and a 21-carat gold oscillating weight, bevelled and polished edges, blued screws | Separate bridges instead of a three-quarter plate, a plain rotor, or unfinished edges under magnification |
| movement | Flyback behaviour | With the chronograph running, pressing reset returns the hand to zero and restarts it immediately, without stopping first | The reset pusher does nothing while running, which indicates a standard chronograph rather than the flyback calibre 37-01 |
| case | Case dimensions and finish | 42mm across and 14.6mm high, polished and satin-brushed steel, screwed crown, water resistant to 10 bar | A uniformly polished case with no brushed surfaces, or a push-in crown |
Common legitimate replacements
- Straps and the folding clasp are consumables. Glashütte Original supplies calfskin, fabric, rubber and the steel bracelet for this case, so any of them can be original.
- Crystals are replaced after impact and a replacement affects value only if it is not a genuine part.
