Problems solved by technology

[0006] However, in a diver's watch having such a bezel, the display area including the dial is reduced in order to suppress enlargement, which may make it difficult to read information from the diver's watch.

no. 1 Embodiment approach

[0021] like Figure 1 to Figure 7 As shown, the electronic timepiece 1 is a diving quartz watch worn on the user's wrist. A diving quartz watch is a type of diving watch. The electronic timepiece 1 has an exterior case 2 as a case, a windshield glass 3 and a back cover 4 . A dial 5 , a movement and a pointer 6 are provided in the exterior case 2 . Pointer 6 is driven by the movement. The hands 6 include an hour hand 7 as a first hand, a minute hand 8 as a second hand, a second hand 9 , a first sub-hand 11 , and a second sub-hand 12 . In addition, a date wheel 13 for displaying the date is also provided in the outer casing 2 .

[0022] The exterior case 2 has an opening 2a. The windshield glass 3 is arranged on the opening 2a. Hour hand 7, minute hand 8 and second hand 9 indicate the time. Dial 5 has markings 14 . Marking 14 is the scale of hour hand 7 , minute hand 8 and second hand 9 . The markers 14 are arranged clockwise from the marker 14a at 1 o'clock to the mark...

no. 2 Embodiment approach

[0061]In the first embodiment, the water detection sensor 31 detects water inflow and outflow, and the pressure sensor 34 detects water pressure which is the pressure of water. The hour hand 7 shows the water depth, and the minute hand 8 shows the diving time. In addition, the electronic timepiece may have an air pressure sensor, an orientation sensor, and a GPS (Global Positioning System: Global Positioning System). Pointer 6 also can indicate air pressure, altitude, azimuth. You can also flexibly use GPS for time correction. Also in this case, it is possible to provide an electronic timepiece in which accurate time, atmospheric pressure, and azimuth information can be easily confirmed due to a large display area.

[0062] Besides that, electronic timepieces can also have illuminance sensors and solar panels. The pointer 6 can also indicate the amount of electricity generated. In this case, it is also possible to provide an electronic timepiece that makes it easy to check...

Abstract

Provided is an electronic watch which can easily confirm time, diving time as diving information, and water depth. The electronic watch includes an exterior case (2) including an opening (2a), a crystal (3) disposed in the opening (2a), an hour hand (7) and a minute hand (8) that indicate the time of day, a dial (5) including an indicium (14), a pressure sensor (34) configured to measure a pressure, and a controller (43) configured to determine a water depth based on the output from the pressure sensor (34), indicate the water depth with the hour hand (7), and indicate an elapsed time with the minute hand (8), the elapsed time being time elapsed after the predetermined water depth value is exceeded.

Description

technical field [0001] The present invention relates to electronic timepieces. Background technique [0002] A watch-type electronic timepiece used for diving is required to display water depth, diving time, etc. in addition to the time. For example, the diver's watch of Patent Document 1 has a pressure sensor and a bezel, and displays the water depth detected by the pressure sensor with long hands. The bezel is in the shape of a ring surrounding the circular dial, and the depth of water is marked on the bezel. [0003] In addition, electronic timepieces in which a diving time scale is engraved on a rotating bezel are generally known. Such a rotating bezel may be provided with a reverse rotation prevention mechanism as described in Patent Document 2 in order to prevent the elapsed time from being displayed shorter than it actually is due to misoperation or the like. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2004-101525 [0005] Patent Document 2: Japanese...
