The Seiko 5 Sports SNXS Series Sports Style SBSA257 (globally distributed under the international reference SRPK91K1) is a highly refined, heritage-inspired mechanical sports watch belonging to the legendary Seiko 5 Sports Collection. Purpose-built as a premium modern tribute to the cult-classic vintage SNXS design layout, this reference updates one of Seiko's most world-renowned everyday formats under a contemporary Everyday Carry (EDC) design directive. The watch is engineered inside a beautifully sculpted 37.4 mm stainless steel case that features elegant, fluid cushion contours blending satin-brushed top surfaces with mirror-polished flanks. Shifting the case architecture to achieve a lower center of gravity, it measures a balanced 12.5 mm in thickness and a tight lug-to-lug length of 44.7 mm, allowing it to sit exceptionally flush and centered against the skin, paired with a newly developed metal bracelet that masterfully weaves hairline and mirror finishes for a look that is both fresh and nostalgic. The primary visual anchor is its magnificent sporty ivory "beige chinos" cream dial face, delivering a warm, neo-vintage canvas that contrasts vividly with a bright 1970s-inspired orange second hand. Powering this versatile everyday machine is the trusted, in-house Calibre 4R36 automatic movement, operating at a frequency of 21,600 vibrations per hour and providing a reliable 41-hour power reserve with manual winding and stop-seconds hacking capacity. Because this specific reference code is a Japanese Domestic Market (JDM) exclusive edition, it features a specialized dual-language day-date calendar window at 3 o'clock that allows the user to display the days of the week in either English or traditional Japanese Kanji. To guarantee excellent daily utility, the multi-faceted, non-triangular wide baton hands and matching bar indices are diamond-cut with finely grooved lines and deeply filled with high-intensity LumiBrite compound along their top surfaces for rapid visibility in the dark. Furthermore, the signature crown remains tucked into a low-profile recessed position at 4 o'clock to eliminate wrist bite. Upgraded with an elite 100-meter daily water resistance rating (a major step up from the vintage models' 30m splash-proof rating) and shielded by a curved Hardlex crystal, this Made-in-Japan reference delivers a perfect bridge between classic 1970s tailoring style and rugged mechanical durability.

Don't buy, check HIS github or google collab for EVERYTHING that's in this book. NO SOLUTION
Format: Paperback
I never write reviews, but after this book I need to. DON'T BUY IT. DO NOT BUY THIS BOOK. Feels like a money grab. You are literally paying money for NOTHING buying this book. Long story short: GO TO HIS GITHUB AND GET IT ALL FOR FREE BECAUSE HE DOES NOT PROVIDE SOLUTIONS. GO ON GITHUB OR GOOGLE COLLAB AND CALL IT A DAY. In the intro he makes it seem like you don't need to know much programming or any tbh. He says if you have never programmed you should be able to read this book. HELL NO, I mean yeah you could probably figure it out, but I would not let someone that doesn't know any programming to start with this. I'd probably tell you to learn the basics of python for a week before starting at the very least. He also makes it seem like you don't need much knowledge of physics. Meh, maybe. Anyway the main reason not to buy: IT'S ALL AVAILABLE FOR FREE ON GITHUB THAT HE PUBLISHES FOR FREEEEEE. You can also use google collab, which he has up for FREEE. and if you are are a beginner I'd recommend you go off teh google collab, that way you don't have to deal with downloading anaconda and setting up an enviroment in jupyter which I think can be intimidating for a beginner. And this book doesn't really give much help in setting up everything in jupyter notebook. Also another point. He'll lead you through an example each lesson, but for the exercises he has you working on he doesn't provide a solution ANYWHERE. like why tf would you buy this book? How do you expect to learn with no feedback? You need to search online for ways to solve these problems, which I think is not a bad skill to have, but if you are new to a subject or trying to learn and you pay for a book why can't i at the very least get some solutions. even math textbook give you solutions, because the understanding is that you can make your own attempt and CHECK TO SEE IF YOU ARE RIGHT. DUHH !

Solid Metal Razor
Color: Polished Silver
I’ve been using this for months to clean up for light dermaplaning, and I really like it. The metal handle feels solid and easy to control, which makes it feel safer than the cheap plastic razors. The blades are sharp but gentle if you use a light hand. It also comes with a lot of replacement blades, which is nice since you don’t have to replace the whole razor and it saves you a ton of money. It took me a try or two to get used to the weight, but now I prefer it. Overall, it feels well-made and works exactly as expected.
