  • What’s the best way to clean my Locman watch?

    We recommend keeping the watch as far away as possible from contact with other watches or materials that may damage the appearance (scratching or denting of the glass, case, bracelet ...). Pay special attention to the strap.

    How do I ensure I get the best wear from the strap?

    The strap is the component most prone to wear and tear, for a number of reasons: the material, daily use, climate, wearer perspiration. Avoid, wherever possible, any contact with additives that may contain alcohol or chemical products, including perfumes, solvents, detergents, etc..

    What should I use for daily cleaning?

    We recommend quick daily cleaning of the case with a soft, slightly damp suede cloth or a synthetic cloth of the type used for cleaning eyewear. Pay special attention to leather watch straps: in this case don’t use damp cloths, to avoid any contact with water.

    How do I adjust the strap to my wrist size?

    If you contact your nearest Dealer or Service Centre, they will adjust the strap for you.

  • What is a quartz movement?

    A quartz movement is one driven by a battery that sends out electrical current. This generates vibrations in the quartz crystals. The constant frequency of the vibrations (32,768 times a second in a standard wristwatch) triggers a very precise movement.

    What is a mechanical hand-wound movement?

    Turning the watch crown clockwise engages the ratchet which, in turn, acts on the drum of the barrel, thus compressing and winding winds the mainspring. The driving force that the mainspring imparts to the going train via the escapement, drives the balance wheel which, coupled to the hairspring, oscillates around its point of equilibrium. The energy is in turn transferred via the dial train to the hands, causing them to advance.

    What is a self-winding mechanical movement?

    In a self-winding mechanical watch, the crown and ratchet are replaced by a weight or rotor that oscillates in a special housing each time the wearer’s wrist moves. The weight is connected by a staff to a ratcheted winding mechanism attached directly to the barrel containing the mainspring. Arm motion moves the rotor, which acts on the ratcheted winding mechanism, thus compressing and winding the mainspring.

    What is the difference between looking after a watch with a hand-wound movement and one with a self-winding movement?

    A mechanical watch can keep time precisely, but this will not be regular over time. To adjust the mechanical movement correctly, the force transmitted by the mainspring to the going train must be sufficient and regular so as to ensure that the hairspring reaches the right amplitude and the balance wheel oscillates correctly. So it is best to wind the watch before putting it on, turning the crown clockwise for at least 25–30 complete rotations. A variation in rate of +/- 15 seconds per day is the best adjustment that may be achieved for a mechanical movement. Nonetheless, depending on how the wearer uses the watch, the difference may vary up to +/- 40 seconds a day. For further information, contact your nearest Dealer or Service Centre.

    Why is the seconds hand in my quartz chronograph oscillating?

    When the seconds hand in a quartz chronograph is reset and seems to move from side to side as if it were oscillating, this is due to the mechanical tolerance crucial for the proper functioning of the actual mechanism, which is supported by a highly reliable electronic movement. No shock absorbers are fitted in an electronic quartz chronograph and the perceived oscillation is attributable to the minimum clearance required for the gear train inside. For further information, contact your nearest Dealer or Service Centre.

    Why does the seconds hand on my quartz chronograph not point to 12 o’clock when I reset it?

    Shock, incorrect use of buttons, or replacing the battery may cause a misalignment of the chronograph hands. This happens because the weight of the inner ball bearing exceeds the strength of the magnetic system. The hands can be easily realigned by following the procedure you will find outlined in the warranty booklet you received with the watch. For further information, contact your nearest Dealer or Service Centre.

    Is it possible to change the strap on my Locman 3000?

    As this product dates back more than ten years, we are only able to offer the original strap in black, thereby ensuring the technical efficiency and water tightness of the watch. For further information, contact your nearest Dealer or Service Centre.

  • Titanium

    Titanium is a metal found in the Earth’s crust. Hardened titanium is 30% stronger but approximately 40% lighter than steel, and is 100% recyclable. Thanks to its biocompatible nature, titanium virtually wipes out risks of intolerance connected to its use. Exposed to the atmosphere, titanium develops an invisible oxide film making it resistant to corrosion from salt water or perspiration.

    316L Stainless Steel

    Locman prefers to make all its components from the highest grade of stainless steel, which is part of the 316L family. This steel is most resistant to corrosion, offers unbeatable solidity and offers the biocompatibility required for its use in the medical field.

    Sapphire-Treated Glass

    Locman watches are fitted with tempered silicon oxide for its excellent transparency. This glass is then treated with aluminium oxide (sintered sapphire) which protects and makes it scratch proof without altering transparency.

    Carbon Fibre

    Carbon fibre is a very fine, thread-like structure composed of carbon, used in a wide variety of materials known as composites. Carbon fibre is typically lightweight, high strength, low density, and offers heat insulation, resistance to temperature changes and the effect of chemical agents, as well as having good fire resistance. Because of its mechanical characteristics, carbon fibre requires very sophisticated processing technologies when used to make watch cases and dials.

    PVD (Physical Vapour Deposition) Coatings

    This process is performed under vacuum. Microscopic particles are deposited on the products by ion bombardment, which gives a porcelain-look effect, with the advantage of being a fine but hard layer that resists corrosion, adheres extremely well, and offers a wide choice of colours. Thanks to the inert nature of PVD, the risks of intolerance arising from its use are almost non-existent.

    Silicon straps

    Locman straps in pure silicon are extremely biocompatible with the human body and are preferred for their excellent hypoallergenic qualities. Following contact with salt water or in case of heavy perspiration, we recommend rinsing in fresh water. Particularly harsh chemical creams and fragrances may alter the colour of silicon. For routine cleaning, we recommend mild soap

    Leather straps

    The leather straps are delicate and immersion in water can make them brittle, leading to breakage. To protect the leather finish and colour, avoid contact with perfumes and creams. The life of a strap will depend on how you care for it, how it is worn, and the climate in which it is worn.
