Monochrome Guilloche Credor Traveller
Seiko Credor Signo Retrograde, GMT, Guilloche: Factory Serviced

- Day-Date
- GMT / Second TimeZone
WHY WE LOVE IT? One of the most complicated automatic-movements ever used by Seiko / Credor under a sophisticated monochrome guilloche-dial, in a heavy and rare platinum-case.
Obviously the absolute top-model in the Signo-line used for the complicated automatic-cal4S77: in a heavy and high-quality platinum-case. The movement comes with around 50h power-reserve, a retrograde day-indicator (3 o'clock), a date-indicator (6 o'clock) and a 2nd timezone / GMT (9 o'clock). Furthermore, the hour could be set independently for the traveller and timezone-adjustment. Special: the reference is the top-model as indicated by the triple-nine in the catalogue-reference: GBBG999, so it is a rare one in any case but even more interesting it seems to be one of the first of the complicated cal4S77: made in 1996-Dec (approx) according to our notes and research and thus almost exactly 20y old: neo-vintage.
The watch was serviced by its manufacturer Seiko (Credor), Japan in 2025-Sep and is of course running precise and reliable in all functions -- guaranteed by Seiko until 2027-Sep.
Presented with its original Credor strap (new & unused), a new custom-made strap, its box and the Credor service-paper.
