Citizen Zenshin CA4610-85M Super Titanium Chronograph
The CA4610-85M is a light chronograph for people who do not want to wind a watch or book a battery change. Citizen’s Eco-Drive calibre B620 charges from light. The case and the integrated bracelet are Super Titanium, not stainless steel. It is a regular-production Zenshin, not a numbered limited edition.
Citizen’s own sheets call the dial blue. In the listing photos it is a textured light blue that reads turquoise, with black subdials and a black tachymeter ring. One European colour filter lists this reference as green. That does not match the photos or Citizen Canada, which calls the dial blue. Do not order it expecting a green dial.
The layout is a three-register chrono. The 60-minute counter sits at 9, the 24-hour register at 3, and the running seconds at 6, with TITANIUM printed on that lower subdial. The date window is near 4:30. Applied silver indices and silver hands sit on the textured ground. The tachymeter is printed on the fixed chapter ring. It does not rotate.
What the calibre and case actually do
B620 is a solar quartz chronograph. It times to 1/5 of a second, up to 60 minutes, and shows the date plus a 12/24-hour indication. Citizen’s European sheet lists about 270 days of reserve from a full charge, and the Hong Kong sheet says about nine months. Those are the same claim in two units. Rate on that European sheet is about +/−15 seconds a month, which is quartz, not a mechanical daily rate. Some Citizen marketing lines say “split-second chronograph.” The published functions are a normal 1/5-second chrono. This is not a rattrapante.
The case is 42.5 mm and silver-tone Super Titanium with a Duratect coating. Citizen’s European and Hong Kong sheets list thickness at 11.6 mm, which is also the figure on this listing. Some retailer pages say 11.8 mm. Treat 11.6 mm as the maker’s figure. Weight is 101 g on the European sheet and 102 g on Citizen Canada. A few shops say about 103 g. There is no single weight to publish.
Crystal is sapphire. Water resistance is 100 metres, or 10 bar. That covers rain, a shower, and swimming. It is not a 200 metre diver. The crown is a pull-out sitting between two chronograph pushers, with no crown guards. The case back screws down. It is solid, not an exhibition back.
The bracelet is integrated Super Titanium with a fold-over clasp and push buttons. Because the bracelet is integrated, this is not a 20 mm leather-strap swap. Do not order a strap from a guessed lug width. The case back is engraved ECO-DRIVE, BASE TITANIUM, SAPPHIRE, DURATECT, W.R.10BAR, B620-0097H01, and JAPAN MOV’T. The serial in that photo reads 123456789. That is a catalogue placeholder, not the number on the watch we send.

Frequently asked questions
Is the Citizen CA4610-85M solar or automatic?
Solar quartz. Eco-Drive calibre B620 charges from light. There is no rotor and no mainspring. A watch left in a drawer for many months will stop until it sees light again.
What colour is the CA4610-85M dial?
Textured light blue, reading turquoise in these photos, with black subdials. Citizen Canada calls the dial blue. Do not use a shop filter that labels this reference green.
What size is the CA4610-85M?
42.5 mm wide. Thickness is 11.6 mm on Citizen’s European and Hong Kong sheets. Some retailer pages say 11.8 mm and about 44 mm lug-to-lug. Those lug-to-lug figures are not on the Citizen spec tables used here, so this page does not treat 44 mm as confirmed.
Does the CA4610-85M need a battery change?
Not in normal use. Keep it where it sees light. A full charge is about nine months, listed as 270 days on Citizen’s European sheet. The movement has a low-charge warning.
Is 100 metres enough for swimming?
Yes for swimming and rain. It is not a screw-crown 200 metre diver. Rinse it after salt water. The crown is a pull-out between two pushers.
Can I fit a leather strap to the CA4610-85M?
Not in the usual way. The bracelet is integrated into the Super Titanium case. A standard 20 mm or 22 mm strap will not drop in. Buy it as a bracelet watch.
Is the case-back number 123456789 the serial I will receive?
No. That engraving is a catalogue sample. The case back on the photo also reads B620-0097H01, BASE TITANIUM, and JAPAN MOV’T. Those markings describe the model. The placeholder serial does not.
