The Orient Stretto RN-TX0305S is the white-dial solar chronograph in Orient’s Contemporary / Stretto line: a 40 mm steel sports-dress watch that charges from daylight or indoor light and times events to a fifth of a second. If you want a panda-style Orient chronograph that does not need a battery swap on a calendar, this is the reference to look at in Australia.
Official catalogues list it as RA-TX0305S as well as RN-TX0305S. Same watch. The case is steel, not gold-tone; the dial is white with dark subdials, not silver. Older listing copy on this page called it a silver dial. That was wrong.
Who the RN-TX0305S is for
This is a weekday watch for someone who likes a chronograph layout but does not want to wind or set a mechanical every few days. The 40 mm width and 48.2 mm lug-to-lug sit closer to a dress case than a dive watch. The five-row steel bracelet and push-button trifold clasp keep it in office clothes; lume on the hands and indexes covers a dim car park at night.
It is not a 200 m diver. Water resistance is 50 m / 5 bar: rain, washing up, and swimming, not scuba. If you need a rotating bezel and screw-down crown, look at Orient’s Kamasu / Mako automatics instead.
Solar chronograph without the bulk
Calibre VS752 is Orient’s in-house solar quartz chronograph. Official specs: about six months of running time from a full charge, accuracy of +20 to −20 seconds per month, 1/5-second stopwatch with a 60-minute register, running seconds, a 24-hour indicator, and a date. The dark subdials also act as the light receptors, which is why they read a little purple off-angle rather than dead black.
You still need light. Leave it in a drawer for half a year and it will stop; a few hours on a windowsill or under a lamp brings it back. There is no monthly battery ritual, which is the whole point of buying solar rather than a standard quartz chrono.
White panda dial, sapphire, steel bracelet
The main dial is white with applied baton indexes. Subdials sit at 9 (running seconds), 6 (60-minute chronograph), and 3 (24-hour). The date window is between 4 and 5. Pushers at 2 and 4 run the chrono; the crown is a standard pull/push at 3. A flat sapphire crystal covers the dial. The case back is a solid screw-down plate. Weight is 124 g. Bracelet width is 20 mm, SUS316L steel, trifold deployant with push-button release, sized for roughly 140–200 mm wrists.

Frequently asked questions
What movement does the Orient RN-TX0305S use?
Calibre VS752, Orient’s solar quartz chronograph. It charges from sunlight or indoor light and is specified at about six months of running time when fully charged, with monthly accuracy of +20 to −20 seconds.
Is the RN-TX0305S a white panda dial or a silver dial?
White. Official Orient specs list the dial colour as white. The dark subdials on a light main dial are why many retailers call it a panda. The case and bracelet are silver-tone steel, not gold.
What is the water resistance of the Orient Stretto RN-TX0305S?
50 metres / 5 bar. Fine for rain, sinks, and swimming. Not a dive watch: no rotating bezel, and the crown is pull/push, not screw-down.
Does the RN-TX0305S need a battery change?
Not as a routine. The solar cell recharges the storage cell from light. If the watch sits in the dark for months it can stop; charge it in light rather than opening the case for a disposable cell.
What is the case size of the RN-TX0305S?
40.0 mm across, 11.1 mm thick, 48.2 mm lug-to-lug, 20 mm lug width. Official weight is 124 g. It wears smaller than Orient’s 42 mm Neo70’s solar chronos.
