    A

    Allocation
    Market Terms
    The number of specific watch models assigned to an authorized dealer by the brand. Dealers with strong allocation access can source highly sought-after pieces at retail price.
    Arbitrage
    Pricing Terms
    The practice of buying a watch in one market (e.g., auction) and selling it in another (e.g., retail) to profit from price differences. Requires deep market knowledge and fast execution.

    B

    B3AF
    Pricing Terms
    Bottom 3 After Fees. A pricing methodology that identifies the lowest three comparable sold listings on eBay, then subtracts platform fees and shipping costs to calculate the true wholesale floor price for a watch.
    Bezel
    Watch Anatomy
    The ring surrounding the watch crystal. Can be fixed or rotating. Dive watches use a unidirectional rotating bezel for timing; dress watches often have a fixed, polished bezel.
    Box & Papers
    Trading Terms
    The original packaging (box) and documentation (warranty card, manuals, receipt) that came with a watch at purchase. A complete set with box and papers typically adds 10-20% to resale value.
    Bracelet
    Watch Anatomy
    A metal band attached to the watch case. Common styles include Oyster (Rolex), Jubilee, President, and integrated designs. Original bracelet condition significantly affects resale value.
    Buyer's Premium
    Pricing Terms
    An additional fee charged by auction houses on top of the hammer price, typically 20-28%. This must be factored into total acquisition cost when buying at auction.

    C

    Caliber
    Watch Anatomy
    The specific movement (mechanism) inside a watch, identified by a reference number. For example, Rolex caliber 3235 is the movement used in the modern Submariner.
    Caseback
    Watch Anatomy
    The rear cover of the watch case. Can be solid (common on Rolex) or transparent/exhibition (showing the movement). Engravings on the caseback may include serial numbers and model references.
    COA
    Trading Terms
    Certificate of Authenticity. A document from a qualified watchmaker, brand service center, or authentication service confirming a watch is genuine. Essential for high-value transactions.
    Complication
    Watch Anatomy
    Any function on a watch beyond basic timekeeping. Common complications include chronograph (stopwatch), date display, moon phase, GMT/dual time zone, and minute repeater.
    Consignment
    Trading Terms
    An arrangement where a watch owner places their piece with a dealer for sale. The dealer sells on behalf of the owner and takes a commission (typically 5-15%) upon sale.
    COSC Certification
    Documentation
    Contrôle Officiel Suisse des Chronomètres. An independent Swiss testing institute that certifies watches meeting strict accuracy standards (-4/+6 seconds per day). COSC-certified movements carry a premium.
    Crown
    Watch Anatomy
    The knob on the side of the watch used to set the time, date, and wind the movement. Screw-down crowns provide water resistance by threading into the case.
    Crystal
    Watch Anatomy
    The transparent cover over the watch dial. Modern luxury watches use sapphire crystal (extremely scratch-resistant) while vintage pieces may use acrylic or mineral glass.

    D

    Demand Velocity
    Pricing Terms
    A measure of how quickly watches of a specific reference are selling in the market, expressed as sales per month. High velocity indicates strong demand and faster inventory turnover.
    Dial
    Watch Anatomy
    The face of the watch displaying the time. Dial variations (color, texture, material) significantly affect value. Rare dial variants can command substantial premiums.

    F

    Flip
    Trading Terms
    A quick buy-and-resell transaction aimed at capturing profit from price differences between markets or temporary underpricing. Successful flipping requires deep market knowledge.
    Flipping
    Market Terms
    Buying a watch with the intent to resell quickly for profit, often taking advantage of market inefficiencies or limited availability. Contrasts with collecting or long-term holding.
    Floor Price
    Pricing Terms
    The lowest realistic price a watch can be expected to sell for in the current market. Mazalgo calculates this using the B3AF methodology based on actual sold data.

    G

    Geneva Seal
    Documentation
    Poinçon de Genève. A quality certification for watch movements made in the Canton of Geneva, verifying craftsmanship, decoration, and accuracy standards. Exclusive to Geneva-based manufacturers.
    Grey Market
    Market Terms
    The secondary market for watches sold outside authorized dealer channels. Includes pre-owned sales, private dealers, and online platforms. Prices are set by supply and demand, not MSRP.
    Grey Market Premium
    Pricing Terms
    The markup above MSRP that a watch commands on the secondary market. High-demand models like the Rolex Daytona can carry premiums of 50-200% over retail.

    H

    Hammer Price
    Pricing Terms
    The final bid price at auction before buyer's premium and taxes are added. The actual cost to the buyer is the hammer price plus all fees.
    Hype Watch
    Market Terms
    A timepiece experiencing demand driven more by social media attention and trend-following than intrinsic horological value. Hype watches can see volatile price swings.

    L

    Lug-to-Lug
    Watch Anatomy
    The total length of the watch case measured from the tip of one lug to the opposite lug. This measurement determines how a watch wears on the wrist — more important than case diameter for fit.

    M

    Margin
    Pricing Terms
    The difference between the purchase price and sale price of a watch, expressed as a percentage. Healthy margins in watch trading typically range from 8-25% depending on volume and brand.
    Market Mover
    Market Terms
    A watch reference experiencing significant price changes — either rapid appreciation or depreciation. Tracking market movers helps dealers time buy and sell decisions.
    Market Value
    Pricing Terms
    The current price a watch would fetch in an arms-length transaction between willing buyer and seller. Determined by recent comparable sales, condition, and completeness.
    Memo
    Trading Terms
    A short-term consignment arrangement between dealers where watches are sent 'on memo' for inspection or to show to potential buyers, with the expectation of return or payment within a set period.
    Movement
    Watch Anatomy
    The internal mechanism that powers the watch. Types include automatic (self-winding via rotor), manual (hand-wound), and quartz (battery-powered). Movement quality is a primary value driver.
    MSRP
    Pricing Terms
    Manufacturer's Suggested Retail Price. The price set by the watch brand for authorized dealer sales. Many popular models trade above MSRP on the secondary market.

    N

    NOS
    Market Terms
    New Old Stock. A watch that was manufactured years ago but never sold or worn. NOS pieces are highly collectible, especially discontinued references, as they represent factory-fresh condition.

    P

    Power Reserve
    Watch Anatomy
    The length of time a fully wound watch will run before stopping. Typical luxury watches have 40-72 hour reserves, while some high-end pieces exceed 10 days.
    Pre-Owned
    Market Terms
    A watch that has been previously sold and worn. Condition, service history, and completeness (box, papers) significantly affect pre-owned value.
    Provenance
    Trading Terms
    The documented history of ownership and origin of a watch. Strong provenance — especially celebrity or historically significant ownership — can dramatically increase value.
    Purchase Agreement
    Documentation
    A formal document outlining the terms of a watch sale including price, condition, return policy, and any warranties. Essential for dealer-to-dealer and high-value private transactions.

    R

    Reference Number
    Documentation
    A unique alphanumeric code assigned by the manufacturer to identify a specific watch model and its specifications. For example, Rolex 126610LN identifies the current-production black Submariner Date.
    Rotor
    Watch Anatomy
    A semicircular weight in automatic movements that swings with wrist motion to wind the mainspring. Custom or decorated rotors are a hallmark of high-end watchmaking.

    S

    Serial Number
    Documentation
    A unique identifier engraved on the watch case, specific to that individual piece. Used to verify authenticity, track service history, and confirm the watch hasn't been reported stolen.
    Service History
    Documentation
    A record of all maintenance and repairs performed on a watch, ideally by authorized service centers. Complete service history with documentation increases buyer confidence and resale value.

    T

    Trust Score
    Trading Terms
    A rating assigned to buyers or sellers based on transaction history, feedback, and verification status. Higher trust scores reduce counterparty risk in watch trading.

    W

    Waitlist
    Market Terms
    A queue maintained by authorized dealers for high-demand watches with limited production. Waitlist times for popular models like the Rolex Daytona can exceed several years.
    Warranty Card
    Documentation
    The official card provided by the brand at purchase, documenting the watch reference, serial number, purchase date, and selling dealer. A stamped warranty card is a key completeness factor for resale.
    Wholesale Price
    Pricing Terms
    The price a dealer pays to acquire a watch from another dealer, typically below retail and secondary market prices. Wholesale transactions require established trust and volume.
    WTB
    Trading Terms
    Want to Buy. A post or listing from a buyer actively seeking a specific watch. WTB posts on forums like Reddit r/watchexchange and WatchUSeek are key demand signals for dealers.
    WTS
