  • Product Description
    Product Specifications

    The Sinn 903 Collection is a family of navigation watches. Each of the watches would make a reliable travelling companion with their perfect orientation in space and time. All of the 903 watches have the capacity to help the wearer to solve the most important arithmetic functions. The dials of the 903 watches are some of the most difficult to produce, requiring over 30 separate steps due to their complexity. Sinn watches are known for using high-quality movements and materials, and the 903 watches are no exception. The collection contains a variety of dial colours and movements to ensure that the 903 collection contains the perfect timepiece for every collector. 

    Core Features of the 903 Collection:

    • The 903 watches are designed to be the perfect travelling companion with their eye-catching dial design and ability to solve mathematical problems
    • Each watch uses sapphire glass to protect the dial. The glass has anti-reflective treatment on both sides.  
    • The watches all have a transparent case back made of sapphire glass that has anti-reflective treatment on the interior. This allows the wearer to observe the movement. 
    • Each of the watches features a bezel with a logarithmic scale and slide rule function. This aids the wearer in multiplication and division, calculating proportions and completing various conversions
    • All of the watches in the collection are water-resistant and pressure-resistant to 20 bar and meet the technical requirements for waterproofness, as set out in standard DIN 8310. The watches are also resistant to low pressure. This is aided by the screw-fastened case back and winding screwable crown

    Model Specifications 903.090: 

    • This column wheel chronograph model exhibits a black electroplated dial with a decorative sunburst and three sub-dials. 
    • The dial also features hour and minute hands made of hybrid ceramic luminous elements. The number “12” and baton indices are made of hybrid ceramic luminous elements as well. 
    • A date display features at the 4:30 position. 
    • A polished and satinized stainless steel case frames the dial. The case measures 41mm in diameter. 
    • The silver electroplated bezel features a logarithmic scale and a slide rule function. 
    • A dark brown leather strap with white stitching secures the watch to the wrist. 
    • The watch is powered by an LJP L110 automatic mechanical movement with at least a 60-hour power reserve. It uses 26 jewels and beats at 28,800 semi-osciallations per hour. The movement also features a seconds stop function and it is anti-magnetic as per DIN 8309.

    In addition to our 30 day returns policy all items purchased from October 1st 2024 may now be returned up until 15th January 2025, terms apply.

    We aim for you to be absolutely delighted with your purchase and therefore offer you 30 days to change your mind on your purchase (excludes pre-owned watches). You may do this by using the form provided with your order or otherwise. We will provide a refund of all payment received (not including delivery upgrades), usually within 48 hours of receipt of the product. This will be made to the original payment method. For most payment methods it will take 3-5 working days for this to show on your statement.

    Please ensure items from your order are suitable before wearing as we are unable to accept items which have been worn under our returns policy.

    For UK orders under £500, you may generate a free tracked and insured returns label on the Royal Mail website (opens in a new window). You can print this label and send it back at any local Post Office at no cost to yourself. It is also possible to have the label printed at Post Office using the QR code from the confirmation email. Please retain the proof of postage receipt. Unfortunately we are unable to provide a refund of return postage for returns through other methods, so we recommend printing the free postage label provided. For orders over £500, please consult your receipt for details on how to return. For international returns, you will need to bear the cost of returns postage. Please ensure the watch is returned to us in an unworn, new condition with all the original packaging (manufacturer's manual and guarantee if applicable). Please ensure items from your order are suitable before wearing as we are unable to accept items which have been worn under our returns policy. We reserve the right to make deductions for unnecessary damage caused to the product by yourself.

    We are also able to offer an exchange to a different product if required, please specify this when returning your product.

    If a fault develops with a watch that is outside of the 30 day returns period or is no longer in a new condition the watch can be returned to the manufacturer under the terms of the guarantee (we are an official UK dealer for all brands on our website) so that they can rectify any issues.
