Used for the case, urethane band, and resin back cover.
Biomass plastics are polymeric materials obtained by chemical or biological synthesis using substances derived from renewable organic resources as raw materials, and are expected to reduce the environmental impact in order to realize a recycling-oriented society.
This time, the case and back are made from castor oil, and the band is made from biomass plastic made from corn.
The soft urethane band features a target guide to improve legibility of the direction indicated by the second hand, and is designed with functional beauty to make it easier to understand the direction.
In addition, the dial uses bar indexes with thicker hands for easy reading, improving visibility.
The PRW-61Y has an IP design on the bezel.
The watch also has practical functions such as Multiband 6, which receives radio waves from six stations around the world, and Tough Solar.
This model is packed with high functionality and practicality in just the right size to suit a variety of situations.

Tough Solar (Solar charging system) * Operating time from full charge without solar power generation: When using functions / Approximately 6 months, When in power saving mode / Approximately 25 months 10 ATM water resistance Radio reception function: Automatic reception (up to 6 times / day) (Chinese radio up to 5 times / day) / Manual reception, Received radio waves: JJY, Frequency: 40kHz / 60kHz (Fukushima / Kyushu both stations compatible model) Received radio waves: WWVB, Frequency: 60kHz Received radio waves: MSF / DCF77, Frequency: 60kHz / 77.5kHz Received radio waves: BPC, Frequency: 68.5kHz * If you set the home time setting to a city that can receive radio waves, the station corresponding to the city will be received.
The time difference is set according to the city you select.
*If radio reception is not possible, the watch will operate with normal quartz accuracy (average monthly difference of ±15 seconds).

- Automatic needle position correction function - Needle evacuation function (manual, automatic (when measuring altitude, air pressure, temperature))
World time: Time display for 29 cities (29 time zones, daylight saving time setting function) + UTC (Coordinated Universal Time), Home city swap function, UTC direct call function Direction measurement function: Measures 16 directions and direction angles (0 to 359°), continuous direction measurement (60 seconds), north direction pointer function, magnetic declination correction function, direction correction function (2-point correction)
Altitude measurement function / relative altimeter (measurement range: -700 to 10,000m, 1m unit), altitude difference indicator (measurement range 1: 100m / 5m unit, measurement range 2: 1000m / 50m unit), altitude trend graph display, measurement interval setting function (5 seconds / 2 minutes), altitude memory (manual memory for up to 30 measurement dates, times, and altitudes), automatic recording data (maximum / minimum altitude, auto accumulation (ascent / descent) memory) * The altimeter is a relative altimeter that converts changes in air pressure into altitude
If the air pressure changes due to weather conditions, the measured altitude will also change.
