フットサルネタ

今日は12時から、渋谷駅ビルでフットサル。フットサルは、テニスコート大のフィールドで5人vs5人で行なうミニサッカーだ。

サッカー経験なしで、30過ぎてから始めたためなかなかうまくならないが、毎週やるようになって非常に体調がいい。風邪もひかなくなった。

体調維持は、責任者だから当然。

何歳まで続けられるかわからないが、なるべく長く続けていきたい。

←先週の江東区大会メンバー（女性入れたミックスの試合）。6チーム中3位と健闘。

  153. PBN sites
    We create a system of privately-owned blog network sites!

    Pros of our private blog network:

    We execute everything so GOOGLE does not understand that THIS IS A self-owned blog network!!!

    1- We acquire domain names from various registrars

    2- The leading site is hosted on a VPS server (Virtual Private Server is rapid hosting)

    3- Additional sites are on different hostings

    4- We attribute a distinct Google profile to each site with verification in Search Console.

    5- We develop websites on WordPress, we don’t employ plugins with assistance from which Trojans penetrate and through which pages on your websites are produced.

    6- We don’t reiterate templates and utilise only exclusive text and pictures

    We never work with website design; the client, if desired, can then edit the websites to suit his wishes

  160. Understanding COSC Certification and Its Importance in Watchmaking
    COSC Certification and its Stringent Standards
    Controle Officiel Suisse des Chronometres, or the Controle Officiel Suisse des Chronometres, is the official Switzerland testing agency that certifies the precision and accuracy of wristwatches. COSC validation is a sign of quality craftsmanship and trustworthiness in timekeeping. Not all timepiece brands seek COSC certification, such as Hublot, which instead sticks to its own stringent criteria with mechanisms like the UNICO calibre, achieving comparable accuracy.

    The Science of Precision Timekeeping
    The core system of a mechanical watch involves the mainspring, which delivers power as it loosens. This system, however, can be susceptible to external factors that may impact its precision. COSC-certified mechanisms undergo demanding testing—over 15 days in various circumstances (5 positions, three temperatures)—to ensure their resilience and reliability. The tests assess:

    Average daily rate accuracy between -4 and +6 seconds.
    Mean variation, maximum variation levels, and effects of temperature variations.
    Why COSC Certification Matters
    For watch enthusiasts and connoisseurs, a COSC-validated watch isn’t just a piece of technology but a testament to enduring quality and accuracy. It signifies a timepiece that:

    Presents exceptional reliability and accuracy.
    Provides guarantee of quality across the entire design of the watch.
    Is apt to retain its worth more effectively, making it a smart investment.
    Famous Timepiece Manufacturers
    Several well-known manufacturers prioritize COSC accreditation for their watches, including Rolex, Omega, Breitling, and Longines, among others. Longines, for instance, provides collections like the Record and Soul, which feature COSC-accredited movements equipped with advanced materials like silicon equilibrium suspensions to boost durability and efficiency.

    Historic Background and the Evolution of Chronometers
    The concept of the timepiece dates back to the need for exact timekeeping for navigation at sea, highlighted by John Harrison’s work in the 18th cent. Since the formal foundation of COSC in 1973, the accreditation has become a standard for judging the precision of high-end watches, sustaining a tradition of superiority in watchmaking.

    Conclusion
    Owning a COSC-certified timepiece is more than an visual choice; it’s a commitment to quality and accuracy. For those valuing precision above all, the COSC validation provides tranquility of thoughts, ensuring that each accredited timepiece will operate reliably under various circumstances. Whether for personal contentment or as an investment, COSC-accredited timepieces distinguish themselves in the world of horology, bearing on a legacy of precise chronometry.
