While the first swiss manufacturers to propose a diver&#8217;s watch chose to develope a case with an outer rotating bezel (Rolex, Blancpain), Seiko chose another technical solution which would become popular in Japan (Citizen Auto Dater, Orient King Diver) : an inner rotating bezel triggered by the crown. <br>The SilverWave was born, as a declination of the Seikomatic or the Sportsmatic. We will focus here on the Seikomatic J12082 version.<br><br><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33%\">\n<h2 class=\"wp-block-heading\">Presentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The design of this SilverWave is absolutely jawdropping. The case is simple and elegant and leaves room for the dial and the inner bezel.  There is only one crown to set the time and adjust the bezel, in opposition to the 2 crowns generally seen on watches with an inner bezel. <br>The watch only displays time and as usual on most Seiko, you can&#8217;t wind the mainspring manually.<br><br><br><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33%\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"2000\" src=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934.webp\" alt=\"\" class=\"wp-image-20875\" srcset=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934.webp 2000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-300x300.webp 300w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-1024x1024.webp 1024w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-150x150.webp 150w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-768x768.webp 768w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-1536x1536.webp 1536w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-12x12.webp 12w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-400x400.webp 400w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-1000x1000.webp 1000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1934-100x100.webp 100w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33%\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"2000\" src=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524.webp\" alt=\"\" class=\"wp-image-20332\" srcset=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524.webp 2000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-300x300.webp 300w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-1024x1024.webp 1024w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-150x150.webp 150w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-768x768.webp 768w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-1536x1536.webp 1536w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-12x12.webp 12w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-400x400.webp 400w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-1000x1000.webp 1000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1524-100x100.webp 100w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"2000\" src=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926.webp\" alt=\"\" class=\"wp-image-20867\" srcset=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926.webp 2000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-300x300.webp 300w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-1024x1024.webp 1024w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-150x150.webp 150w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-768x768.webp 768w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-1536x1536.webp 1536w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-12x12.webp 12w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-400x400.webp 400w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-1000x1000.webp 1000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1926-100x100.webp 100w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\">The dial &amp; hands<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There were 2 versions of the dial, the most popular is the rarer one with the crossed pattern, something which is quite unique I think. The SilverWave mention is written with a cursive font and will be kept until the quartz era SilverWaves from the 80&#8217;s. <br>The second version of the dial lacks that crossed pattern but has a &#8220;Water 50 proof&#8221; mention just under the SilverWave name. <br>Each hour marker has a luminous square on its inner side.<br>The inner bezel has a standard 60-minute scale and can be white or black.<br>The hands are Dauphine with luminous matter at their centres. I think they are the same than the ones on the Alpinist and the Weekdater 6206-8990. <\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\">The case<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The case is made of stainless steel and has a screwed back. <br>The back has the SilverWave logo which reminds of course the great wave of Kanagawa from Hokusai. The crown is quite big so you can handle it easily (too easily maybe, when you&#8217;re diving ?) and is common to several Seiko models with an inner bezel (Seiko 6217 for example).<br>The crystal is an acrylic glass, pressed on the case and held by the outer bezel. Its profile is particular and maintains the inner rotating bezel in place. There are 18 mm between the lugs.<br><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"2000\" src=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923.webp\" alt=\"\" class=\"wp-image-20864\" srcset=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923.webp 2000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-300x300.webp 300w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-1024x1024.webp 1024w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-150x150.webp 150w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-768x768.webp 768w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-1536x1536.webp 1536w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-12x12.webp 12w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-400x400.webp 400w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-1000x1000.webp 1000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/06\/DSCF1923-100x100.webp 100w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\" \/><\/a><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"2000\" src=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516.webp\" alt=\"\" class=\"wp-image-20324\" srcset=\"https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516.webp 2000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-300x300.webp 300w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-1024x1024.webp 1024w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-150x150.webp 150w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-768x768.webp 768w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-1536x1536.webp 1536w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-12x12.webp 12w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-400x400.webp 400w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-1000x1000.webp 1000w, https:\/\/www.watchandvintage.fr\/wp-content\/uploads\/2026\/04\/DSCF1516-100x100.webp 100w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\">The movement<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Seikosha 603 movement is the one usually found in the Seikomatic, in its 20 jewels version.
