The development of a diver\u2019s watch with a see-through case back, a feature that tends to add thickness, presented its own challenges. The new watch needed to maintain the high level of water and shock resistance that Prospex usually achieves with a closed case back while also keeping the profile thin. By reconsidering the case structure and using the slimline Caliber 6L37, Seiko created what is its thinnest mechanical diver\u2019s watch currently (12.3mm) while adding a view of the movement.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08-1024x682.jpg\" alt=\"Seiko Prospex Marinemaster 100th Anniversary\" class=\"wp-image-21794\" srcset=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08-1024x682.jpg 1024w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08-600x400.jpg 600w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08-300x200.jpg 300w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08-768x512.jpg 768w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08-1536x1024.jpg 1536w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2023\/12\/Seiko_Marinemaster_100_Anniversary_Watch_Insanity_08.jpg 1772w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The new\u00a0<strong>39.5mm case<\/strong>\u00a0design balances functionality and aesthetics thanks to dramatic cham- fering on the bezel and the case, which creates a sleeker and more modernized appearance while retaining the essential profile of the classic 62MAS from 1965.
