These models extend the brand\u2019s range of solar-powered chronographs, but this time with even greater precision. As their name suggests, the stopwatch on the new Speedtimers can measure time to the nearest 1\/100th of a second. However, this isn\u2019t the only update. Refreshing the dial design of the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-speedtimer-watches-c-24_1236_3013\/\">Speedtimer collection<\/a>, these new models also feature four subdials instead of the usual three. Its beautiful albeit quirky appearance makes it a great representation of Seiko\u2019s professional and innovative timekeeping heritage. Alongside their wacky new design, there is lots to love about the new Seiko Prospex 1\/100th Second Speedtimers. So, let&#8217;s get stuck into their core specifications.<\/p>\n\n\n\n<h3>Core Specifications of the New Seiko Prospex 1\/100th Second Speedtimers<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1.jpg\"><img loading=\"lazy\" width=\"1024\" height=\"683\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-1024x683.jpg\" alt=\"New Seiko Prospex 1\/100th Second Speedtimers\" class=\"wp-image-53207\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-1024x683.jpg 1024w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-300x200.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-768x512.jpg 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-1536x1025.jpg 1536w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-2048x1366.jpg 2048w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-1110x740.jpg 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-930x620.jpg 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-750x500.jpg 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-510x340.jpg 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-360x240.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/PSX_ST_SFJ001-1-120x80.jpg 120w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignleft size-large is-resized\"><a href=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped.jpg\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-644x1024.jpg\" alt=\"\" class=\"wp-image-53198\" width=\"168\" height=\"267\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-644x1024.jpg 644w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-189x300.jpg 189w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-768x1221.jpg 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-966x1536.jpg 966w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-1289x2048.jpg 1289w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-1110x1764.jpg 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-930x1478.jpg 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-750x1192.jpg 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-510x811.jpg 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-360x572.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-300x477.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped-120x191.jpg 120w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122327-6251_cropped.jpg 1510w\" sizes=\"(max-width: 168px) 100vw, 168px\" \/><\/a><\/figure><\/div>\n\n\n\n<h4>Dial and Case<\/h4>\n\n\n\n<p>The dial is one of the features that has certainly attracted the most attention. Subverting the need for a \u2018main dial\u2019, the new Speedtimers instead divide the watch\u2019s functions into four subdials.<\/p>\n\n\n\n<p>Although this fundamental design is universal across all the new Speedtimers, there are four different colourways to choose from. Each of these versions emphasises the design differently. For instance, the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-panda-one-hundredth-of-a-second-speedtimer-solar-chronograph-sfj001p1-p-122321\/\">\u2018panda\u2019 model (SFJ001P1)<\/a> of this range draws more attention to the quirkiness of the subdials. With its lightly-textured silver-white dial, the eye is immediately drawn to the contrasting black subdials. However, for a look where the subdials are not the main focus, there is a <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-black-on-black-one-hundredth-of-a-second-speedtimer-chronograph-sfj003p1-p-122324\/\">\u2018black on black\u2019 model (SFJ003P1)<\/a>. For a nice middle ground, the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-one-hundredth-of-a-second-2023-world-athletics-limited-edition-speedtimer-sfj007p1-p-122330\/\">limited edition all-over black model (SFJ007P1)<\/a> features a more intricate texture and gold details to accent the design. Moreover, the fourth model features a <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-khaki-stripe-one-hundredth-of-a-second-limited-edition-speedtimer-sfj005p1-p-122327\/\">khaki dial with red-accented black subdials (SFJ005P1)<\/a>, providing a little more depth to the design.<\/p>\n\n\n\n<p>Housing each of these designs is a sturdy stainless steel case that measures 42mm in diameter. On the limited edition model (SFJ007P1), this case has a hard black coating. The robustness of this case also seals in 100 metres (10 bars) of water resistance across the series.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model.png\"><img loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-1024x576.png\" alt=\"New Seiko Prospex 1\/100th Second Speedtimers\" class=\"wp-image-53195\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-1024x576.png 1024w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-300x169.png 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-768x432.png 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-1536x864.png 1536w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-2048x1152.png 2048w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-1110x624.png 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-930x523.png 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-750x422.png 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-510x287.png 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-360x203.png 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/Seiko_SFJ005_Model-120x68.png 120w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright size-large is-resized\"><a href=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped.jpg\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-649x1024.jpg\" alt=\"\" class=\"wp-image-53201\" width=\"171\" height=\"271\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-649x1024.jpg 649w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-190x300.jpg 190w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-768x1212.jpg 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-973x1536.jpg 973w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-1297x2048.jpg 1297w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-1110x1752.jpg 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-930x1468.jpg 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-750x1184.jpg 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-510x805.jpg 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-360x568.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-300x474.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped-120x189.jpg 120w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2023\/06\/product122330-5984_cropped.jpg 1495w\" sizes=\"(max-width: 171px) 100vw, 171px\" \/><\/a><\/figure><\/div>\n\n\n\n<h4>Movement and Finishing Touches<\/h4>\n\n\n\n<p>The new Seiko Prospex 1\/100th Second Speedtimers are also built with brilliant mechanical technology. Back and better than ever, each model is equipped with Seiko\u2019s in-house solar-powered movement. Its 8A50 chronograph calibre recharges from both natural and artificial lighting. But, without recharging, the watch can still last up to six months from a full charge.<\/p>\n\n\n\n<p>This calibre also allows for ultra-precise time measurement. Impressively, its stopwatch is able to measure to the nearest one-hundredth of a second. To easily control this stopwatch, there is a hammer-shaped button on the side of the case.<\/p>\n\n\n\n<p>Completing each of the watches is a classic stainless steel bracelet. Whilst the bracelet is silver on the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-panda-one-hundredth-of-a-second-speedtimer-solar-chronograph-sfj001p1-p-122321\/\">panda (SFJ001P1)<\/a> and the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-black-on-black-one-hundredth-of-a-second-speedtimer-chronograph-sfj003p1-p-122324\/\">black dial model (SFJ003P1)<\/a>, the other two models put their own spin on it. In keeping with the rest of the design, the bracelet on the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-one-hundredth-of-a-second-2023-world-athletics-limited-edition-speedtimer-sfj007p1-p-122330\/\">limited edition all-over black model (SFJ007P1)<\/a> has a hard black coating. On the <a href=\"https:\/\/www.firstclasswatches.co.uk\/seiko-prospex-khaki-stripe-one-hundredth-of-a-second-limited-edition-speedtimer-sfj005p1-p-122327\/\">khaki model (SFJ005P1)<\/a>, the central links of the bracelet are solid black to contrast the silver outer links.<\/p>\n\n\n\n<p>Specific, sustainable, and slightly quirky, the new New Seiko Prospex 1\/100th Second Speedtimers are very promising. But what do you think of them? Are you a fan of the four-subdial design?
