Timex is an iconic American watch brand with roots dating back to 1854, known for producing durable and affordable timepieces. The brand became a household name through its famous 'Takes a Licking and Keeps on Ticking' advertising campaigns. Timex watches feature various markings on their case backs and dials that can help with identification, though vintage Timex pieces can sometimes be challenging to date precisely due to the brand's enormous production volumes. Understanding Timex markings is particularly valuable for collectors of vintage American-made timepieces.

Serial Number Information
Timex serial numbers and model codes have undergone significant changes throughout the brand's long history. Vintage Timex watches from the mechanical era often feature a model number stamped on the case back that follows a format specific to the production period. These numbers can sometimes be decoded to indicate the movement type, case style, and dial configuration, though the coding systems varied across different eras and product lines.
For mid-century Timex watches (roughly 1950s through 1970s), the case back often displays a multi-digit code that collectors have partially decoded over the years. Various online resources maintained by Timex collector communities provide guides for interpreting these codes, though the information is not always complete or universally agreed upon. The transition from mechanical to quartz movements in the late 1970s and 1980s brought changes to the numbering system.
Modern Timex watches typically use a model reference number (often starting with 'T' or 'TW') that can be looked up on the Timex website or through retailers. These reference numbers are commonly printed on the case back and may also appear on the original packaging and documentation. Unlike some other brands, Timex does not generally publish detailed serial number decoding guides, so dating older pieces often relies on collector knowledge and reference materials.

Common Markings Found on Timex Watches
Model Number Stamp
An alphanumeric code stamped on the case back that identifies the specific watch model or product line. This number is essential for ordering replacement parts and identifying your watch's specifications.
Crystal Press Back SymbolA small symbol on the case back indicating it should be opened with a crystal press tool rather than unscrewed. This marking guides watchmakers on the correct method for case back removal.
Stainless Steel Back StampA marking reading "STAINLESS STEEL BACK" or "ST. STEEL BACK" indicating the case back material. This is commonly found on watches where only the back is stainless steel while the case body may be a different material.
WR 50M / 5 Bar MarkingA water resistance rating of 50 meters (5 bar/ATM), indicating the watch can handle everyday moisture like rain and hand washing. This rating is not suitable for swimming or submersion.
Bar / ATM Pressure RatingA water resistance rating expressed in bar or ATM (atmospheres) instead of meters. One bar/ATM approximately equals 10 meters of water depth in testing pressure.

Frequently asked questions
How can I find the model number on my Timex watch?
The model number on a Timex watch is typically found on the case back, often stamped or engraved. Modern Timex models usually have a reference number beginning with 'T' or 'TW'. On vintage models, the numbering format can vary, and you may need to consult collector resources to interpret the codes correctly.
How do I determine the age of my vintage Timex watch?
Dating a vintage Timex often requires examining the case back model number, the movement type, and design elements such as the logo style and dial layout. Collector communities have compiled partial decoding guides for various Timex numbering systems. Comparing your watch to dated catalog images is often one of the most effective approaches.
Are vintage Timex watches valuable?
While most vintage Timex watches remain relatively affordable, certain models have become collectible and can command higher prices, particularly rare dial variants, military-issued pieces, and early automatic models. Value often depends on condition, completeness, and desirability among collectors. The market for vintage Timex has generally grown as interest in affordable vintage watches has increased.
What movements did Timex use in their mechanical watches?
Timex used a series of proprietary mechanical movements often designated with 'M' numbers, such as the M24 and M25 hand-wound calibers and various later automatic movements. These movements were designed for mass production and affordability. While not typically considered high-grade, they are generally regarded as reliable for their price point.
Where were Timex watches manufactured?
Timex watches have been manufactured in various locations throughout the brand's history. Early production was based in the United States, including factories in Connecticut and Arkansas. Over the decades, manufacturing shifted to various international locations including Scotland, Taiwan, the Philippines, and China. The country of origin marked on the case back can sometimes help with dating.
What does 'WATER RESISTANT' mean on my Timex case back?
The 'WATER RESISTANT' marking indicates that the watch was designed to withstand some exposure to water, though the level of resistance varies by model. Many Timex watches carry a specific water resistance rating in meters or ATM. As with all watches, water resistance can degrade over time, and the original rating may not reflect current capabilities.
Can I get my vintage Timex watch serviced?
Servicing vintage Timex mechanical watches is possible, though finding replacement parts can sometimes be challenging. Independent watchmakers who specialize in vintage timepieces may be able to service the movement and source replacement parts from donor watches. Timex's official service centers primarily handle current models and may not be equipped to service very old pieces.
How can I tell if a Timex Marlin reissue is authentic?
Authentic Timex Marlin reissue watches typically feature the correct model reference on the case back, the Timex branding on the dial and crown, and an appropriate movement for the specific reference. Purchasing from authorized Timex retailers is the most reliable way to ensure authenticity. Given Timex's accessible pricing, counterfeiting of modern models is relatively uncommon but not unheard of.
