The Citizen Exceed CB1145-67A is the slimmest watch in the trio, at only 7 mm.
Citizen has launched three new Exceed Eco-Drive radio watches in Super Titanium, sporting sakura-toned bezels, sapphire crystal, and slim cases. Prices range from ¥132,000 (~$846) to ¥187,000 (~$1,199), with a March 5 release in Japan.

Alongside a new Series 8 model, Citizen has introduced three fresh models under its Exceed lineup in Japan, and they are all scheduled for release on March 5. The new references - ES9375-51B, CB1115-50B, and CB1145-67A - feature Eco-Drive solar tech with multi-band radio timekeeping, and come in slim Super Titanium cases.

The ES9375-51B is the smaller of the trio at 26.6 mm wide and just 7.7 mm thick, weighing 34 grams. It runs on Caliber H060 and supports radio reception in Japan, China, the US, and Europe. Accuracy is rated at ±15 seconds per month when not receiving a signal. The case and bracelet use Super Titanium with Duratect Platinum and Duratect Sakura Pink surface treatments - this gives the bezel a subtle cherry tone that complements the light silver body quite well. Sapphire crystal with clarity coating sits on top, and water resistance is rated at 5 bar. Pricing is set at ¥132,000 (~$846).

The CB1115-50B moves up to a 38.0 mm case and 8.5 mm thickness, powered by Caliber H149. It shares the same Eco-Drive and radio-controlled functionality, along with a perpetual calendar, world time (24-hour difference), direct flight adjustment, and summer time setting. The watch weighs 62 grams and also uses Super Titanium with the same dual-tone surface treatment. Price is ¥132,000 (~$846).

The CB1145-67A is easily the most premium option of the three at ¥187,000 (~$1,199). It uses Caliber H147 and is incredibly slim at 7.0 mm, alongside a 38.0 mm case. The dial is equipped with a textured central pattern with applied Roman numerals, paired with the same light silver and sakura-colored bezel treatment. Weight is 59 grams.

All three models include sapphire crystal, nickel allergy resistance, anti-magnetic protection (JIS type 1), shock detection, automatic hand correction, and a three-year international warranty. They are all manufactured in Japan.
