# Reference: **Model:** Credor "Signo" GCBK983 / 6S37-00D0 **Production Date:** September 2012 **Timestamp:** [https://imgur.com/a/zXshd4a](https://imgur.com/a/zXshd4a) **Album:** [https://imgur.com/a/8xobGbs](https://imgur.com/a/8xobGbs) # Features: **The Rarity.** The last automatic chronograph made by Credor. Don’t worry, as I’m sure Credor will revisit this type of movement eventually - but it has been a while. The GCBK979 on offer today was released in 2011 and discontinued in 2013, marking a 12-year absence of a chronograph in Credor’s lineup. That’s only slightly surprising, given the brand's increasingly dressy direction in recent years. It seems Credor has moved on to Big Dates and ultra-thin Spring Drives, leaving the chronographs to Seiko. I’m largely fine with that, but it is nice to see Credor’s level of finishing applied to sporty watch. **The Dial.** Despite being part of the Singo collection, rather than the Pacific, the sub-dials feature a ship’s wheel motif similar to the one etched into the GCBZ999, which I assume is a tribute to Japan’s maritime legacy. The internal metal accents have all been coated in titanium nitride, giving them an iridescent sheen reminiscent of mother-of-pearl. The purples and turquoises produced by the coating are hard to capture in photos, but you can catch glimpses of them in a few of the shots above. **The Movement.** It’s powered by the 6S37 - the direct successor (and upgrade) to the 6S78 that TAG took inspiration from. It features more jewels, tighter tolerances, and a decorative finish. Credor sensibly opted for an exhibition caseback, giving you a clear view of the Geneva stripes on the bridges and rotor. And while the quoted daily accuracy is the modern Credor standard of -10 to +15 seconds per day, these 6S chronographs are well known to outperform that. My timegrapher certainly agrees with the watch running at +3 seconds per day. # Details: **Condition:** Just serviced. In great condition. No noticeable marks of any significance.
