The storyWhy this reference matters
Attesa is one of those collections Citizen kept to itself in Japan for a long time. It started in 1987 with a brief that was easy to state and hard to deliver: apply to titanium the surface treatments the brand handled better than anyone, and use the line as a laboratory for technical firsts. Nearly forty years on it is still where Citizen launches whatever is not ready for the rest of the catalogue, which is why an Attesa is usually a step ahead on electronics.
The satellite saga began in 2011, when Citizen showed the world's first light-powered, satellite-synchronised watch. In 2014 the F100 calibre cut time reception to three seconds and became the thinnest of its kind; in 2015 the F900 added position as well as time, so the watch could work out which zone it was in by itself. The F950 is the next rung: the same three seconds, a perpetual calendar programmed to 28 February 2100 and world time across thirty-nine zones.
This particular reference arrived in 2025 and brought a change more of form than of substance: it is the first F950 with an octagonal ceramic bezel. It sits on a Super Titanium case treated with black Duratect DLC, and the result is 44 millimetres across by 13.7 tall for 115 grams. In steel, a multifunction watch this size would weigh close to double, and the bracelet would notice before the wrist did.

IdentificationHow to tell it apart
The bezel is this reference's identity card: octagonal, in black ceramic. Earlier F950s, the CC4059-64L or the CC4074-61W, have a round sapphire bezel. If the watch in the listing has a round bezel, it is an earlier F950 and not this one, however large the letters F950 appear in the description.
Within the octagonal series itself there are three cousins that get confused with each other: the CC4104-53E, with titanium carbide Duratect and a silver look; this CC4105-69E, black with Duratect DLC; and the CC4106-74E, limited to 2,000 pieces with blue DLC on bezel and bracelet. The 69E is, quite simply, the black one that is not limited.
On the dial, find the second time zone, the chronograph reading to a twentieth of a second up to 24 hours, and the power reserve indicator. Stated accuracy when it cannot see a satellite is five seconds a month, and water resistance is 10 bar, meaning 100 metres: this is a travel watch, not a dive watch, whatever the shape of the bezel suggests. Weight, 115 grams; sapphire crystal with anti-reflective coating.
CollectingWhat collectors check
Satellite watches deserve a warning you would never give about a mechanical one: there is consumer electronics inside. The receiver module and the cell are service parts and depend on the brand continuing to stock them. Buying a satellite watch that is fifteen years old is a gamble; buying one from 2025 is not, but keep the hourglass in mind when you work out how long you plan to keep it.
Duratect DLC cannot be polished, and this is the rule that saves the most money in this whole entry. It is a hard coating, not a colour plating a workshop can touch up: if someone takes a wheel to a scratch, the layer comes off and grey titanium appears underneath. On a black watch you can see that from the far end of the table. Check the edges of the octagonal bezel and the sides of the links, where it shows first.
Test the reception before you buy. Next to a clear window, the watch should lock on within seconds and correct itself. If it fails, repeat the test outdoors before writing it off: it could be low charge, or simply too much concrete in the way. And put a value on the original box with the spare links, because a Super Titanium bracelet cannot be replaced with just anything, nor extended with links from another model.
Common questionsWhat people ask us about this reference
What is the difference between the Citizen F950 and the F900?
The F950 is the later generation. Both sync by satellite in about three seconds, but the F950 comes in far more compact cases — 44 millimetres against the 47 of the F900 CC9025 — with a perpetual calendar to 2100 and world time across 39 zones.
Does the Citizen Attesa Satellite Wave need a battery?
No. It is Eco-Drive: it charges from natural or artificial light and holds up to eighteen months of reserve, five years with power-save switched on. The only thing replaced, after many years, is the internal cell.
Does the Citizen's GPS work indoors?
It needs a view of the sky. A few seconds by a clear window is enough, though deep inside a building or between tall blocks it may not lock on. With no signal, the movement keeps to five seconds a month.
How much does the Citizen CC4105-69E weigh?
115 grams, with a Super Titanium case and bracelet. That is 44 millimetres across by 13.7 tall: for a watch with GPS, a chronograph and a perpetual calendar, it is one of the light ones.
