    Sized at 38mm, the Neutron is Pinion’s smallest watch to date and features a highly detailed electroplated dial with guilloche decoration as its centrepiece, brushed stainless steel case and is powered by the dependable Swiss made Sellita SW200-1 automatic movement.

    As with all Pinion watches, the Neutron is manufactured in small batches, is designed and built in England, plus customers can choose to personalise their watch with free case back engraving

    Small in size

    Sized at 38mm, the Neutron is Pinion’s smallest watch to date. Whilst it is only 1mm smaller than the previously released Atom 39, a lot of attention has gone into reducing the overall length and height of the watch to make a sleeker and more refined profile when worn on the wrist. The dial aperture has also been reduced by 2mm, meaning the bezel surrounding it is larger and in better proportion to new case design.

    Big on details

    The main feature of the dial is a guilloche pattern, with the outer edge in a circular brushed finish. This is then electroplated to achieve the dial colouring (black, blue, dusty pink). Raised numerals are machined in brass, polished then electroplated in nickel (silver) before being applied by hand to the dial. Batons in a contrasting radium hue are printed and applied with SuperLuminova to aid legibility in low-light conditions. Unlike previous models, which featured the Pinion logo prominently on the dial, The Neutron has opted for a subtle reference to the watchmaker’s name printed on the sloping inner bezel (rehault) to avoid clashing with the core guilloche centrepiece.

    Grooved hands

    The Neutron features diamond-cut brass hands in a polished finish. The hour and minute hands also highlight a subtle etched groove in a contrasting matt finish running along their centre. The hands are nickel (silver) plated and filled with Superluminova to aid legibility.

    Durable Swiss movement

    Powering the Neutron is the dependable Swiss automatic movement – Sellita SW200-1, which has a 38-hour power reserve and will continue to wind the watch whilst it is worn.

    Each movement is regulated by Pinion’s watchmaking team in England over 5 days / 5 positions to a minimum of +/- 5 seconds variation a day to ensure it remains accurate.

    (Note: Earlier versions of this watch had ETA2824-2 movement).

    Buying outside of the UK

    Any orders that are made outside the UK are priced excluding the tax, however, you will be subject to import duty/tax when the item is imported into your country. This includes exporting to EU countries after 1 Jan 2021.

    When you process your order at checkout and enter your country, the price will automatically remove any VAT if it was previously shown.

    DHL will handle the charge for import duty and will typically contact you prior to delivery to arrange payment. Please ensure that when you are requested to make a payment for import duty, you are directed to the DHL website.

    Import duty varies from country to country. Please ensure you check the current rates in your region before ordering.

    If you prefer for Pinion to handle the customs charge, we can do this but will require you to make an additional payment to cover the cost.

    Please note: When making an order, please do not ask us to lower the value of the item which would result in no or less duty to pay as this is illegal.

    UK prices

    i.e. Atom 39 – £990 ( £825 plus 20% VAT – £165).

    Outside UK prices
