Timex Watch Band Size by Model
Timex is the easiest major brand to buy straps for and the easiest to get wrong anyway. The reason it is easy: nearly every full-size men's Timex made today takes a 20mm strap, so one strap rotation covers a whole drawer of Weekenders, Expeditions and Marlins. The reason it goes wrong: the exceptions are scattered through the catalogue, from the 16mm mid-size Weekender to the integrated Ironman straps that take no standard width at all, and Timex's own band-size blog page publishes strap LENGTH charts with not a single per-model width number on it. This page is the missing table. Every row below is confirmed by two independent sources, Timex's own product pages first where they exist.
Timex band width by model
| Model | Case | Band width | Notes |
|---|---|---|---|
| Weekender 38mm (T2N647 and siblings) | 38mm | 20mm | Timex product page lists Band / Lug Width 20 mm |
| Weekender 40mm (TW2W86800, TW2R42400) | 40mm | 20mm | Same 20mm as the 38mm; slip-thru strap |
| Weekender Chronograph 40mm | 40mm | 20mm | Shares the platform's 20mm |
| Weekender mid-size / women's | 31mm | 16mm | The common wrong order: assuming 20mm here |
| Expedition Scout 40mm (T49963, TW4B14100) | 40mm | 20mm | Timex replacement strap for the Scout is 20mm |
| Expedition North Titanium Automatic (TW2V95300) | 41mm | 20mm | One retailer's 18mm contradicted; see flagged row below |
| Expedition smaller references (Field Post Solar 36, Metal Field 39) | 36-39mm | 18mm | The smaller Expedition cases step down to 18mm |
| Expedition digital / Grid Shock | varies | integrated | Molded resin straps; match by model number |
| Marlin Automatic 40mm (TW2T22700 family) | 40mm | 20mm | Two-piece 20mm leather, quick-release on some refs |
| Marlin Quartz 34mm (TW2T45200 family) | 34mm | 18mm | The smaller reissue; not 20mm |
| Easy Reader men's / women's 38mm (TW2R62700) | 38mm | 20mm | Runs on 20mm leather despite the modest case |
| Easy Reader smaller ladies' references | 34mm and under | 16-18mm | Check the reference before ordering |
| Easy Reader Expansion (stretch band) | varies | varies | Self-adjusting expansion band; sized by wrist range, not width |
| MK1 40mm (TW2Y71800 Automatic, TW2Y71100 chrono) | 40mm | 20mm | Band / Lug Width 20 mm on Timex's own spec pages |
| MK1 mid-size | 36mm | 18mm | The smaller MK1 drops a pair of sizes |
| Waterbury Classic 40mm (TW2T27500, TW2U97200) | 40mm | 20mm | Strap and Lug Width 20 mm per Timex and dealers |
| Waterbury Classic 39mm sub-seconds (TW2Y92100) | 39mm | 20mm | 2026 refresh; still 20mm |
| Ironman Classic 30 / most full-size Ironman digitals | 38-42mm | integrated | Molded resin, model-number-specific |
| Ironman standard-lug references (T5K793 family) | full-size | 20mm | Timex's own replacement strap is a 20mm resin strap |
| Ironman mid-size / Essentials | varies | 16mm | Timex sells 16mm replacement straps for the small digitals |
| Q Timex 38mm reissue | 38mm | 18mm | Retro width; not the modern 20mm default |
| Women's and mid-size Timex generally | 34mm and under | 16mm or 18mm | Timex's women's strap shop filters on 16/18/20mm |
One disagreement worth flagging: Delugs' Expedition North strap guide states the watch uses a standard 18mm lug width. Two stronger sources say otherwise: Timex India's own specification page for the TW2V95300 Expedition North Titanium Automatic lists strap width 20 mm, and aBlogtoWatch's hands-on review measures the curved lugs set 20mm apart, tapering to an 18mm buckle. Reddit owners in a strap thread report the same 20mm. Treat 18mm for the Expedition North as wrong; buy 20mm. Everything else in the table matched across at least two independent sources.
The Ironman trap, and the 20mm exception inside it
Most Ironman watches, like most digital Expeditions, use an integrated resin strap: the band is molded to the case's curvature and fixed with pins or screws rather than standard spring bars, so there is no lug width to look up. The fix is the model number stamped on the caseback (T5K195, T5E231 and so on), which indexes Timex's own replacement-strap catalogue exactly. The exception is real but narrow: the Ironman Classic 30 Full-Size (T5K793 family) takes a normal 20mm resin strap on standard spring bars, and Timex's own replacement for it is listed as a 20mm resin strap with normal buckle. An owner-measured Triathlon at 19.8mm between the lugs, relayed in the Q and A on that same Timex page, confirms the 20mm fit on the sibling model. If your Ironman has visible straight lugs and a conventionally pinned strap, it is a 20mm watch; if the strap melts into the case lines, it is integrated and model-number-specific.
The Indiglo question, answered
People ask for the band size of a "Timex Indiglo" as if Indiglo named a model. It does not: Indiglo is the electroluminescent dial backlight Timex has fitted across nearly the whole catalogue since the early 1990s, so a search for it can land on anything from an Easy Reader to an Expedition. The band size follows the model, not the backlight. If the watch is a full-size men's analog Timex with Indiglo, it is almost certainly 20mm; if it is a small ladies' model, 16mm or 18mm; if it is digital, treat it as integrated until the caseback model number says otherwise. The same logic handles the "Timex explorer" searches: there is no current Explorer line, and the watches people usually mean are Expeditions, which are 20mm in the 40mm case and 18mm in the small ones.
Timex's own strap length ranges
Width decides whether the strap fits the watch; length decides whether it fits your wrist, and this is the part Timex itself publishes. From Timex's own fit and blog pages, the length ladder for leather and fabric straps with holes is:
| Men's length | Fits wrist | Women's length | Fits wrist |
|---|---|---|---|
| Short | 6.25 to 6.90 in | Short | 5.75 to 6.40 in |
| Regular | 7.00 to 7.90 in | Regular | 6.50 to 7.20 in |
| Long | 8.00 to 8.70 in | Long | 7.25 to 8.00 in |
| Extra-long | 8.75 to 9.25 in | Men's lengths cover the largest wrists | |
For stretch bands the system is different, because an expansion band self-adjusts across its whole travel. Timex's fit page gives the PerfectFit Expansion band a 5.9 to 8.1 inch range (150 to 205mm) in men's and 5.3 to 7.5 inches (135 to 190mm) in women's, which is also the range printed for typical full-size watch bands on individual product pages like the Weekender 40mm. What that range means for your wrist, and how to measure it, is the strap length by wrist question rather than a width question, so the full method lives there.
The 20mm machine, and how to reuse one strap across a Timex collection
- The 20mm family: Weekender 38mm and 40mm, Expedition Scout 40mm, Expedition North 41mm, Marlin Automatic 40mm, MK1 40mm, Waterbury, Easy Reader 38mm, standard-lug Ironman. This is the same 20mm used by Hamilton Khaki Field and most Samsung Galaxy Watches, so straps circulate across brands freely.
- The 18mm family: Marlin 34mm, Q Timex 38mm, MK1 mid-size, the small Expeditions. Also the Casio F-91W standard covered on the Casio strap size chart.
- The 16mm family: mid-size and women's Weekender, small Ironman replacements. The thinnest aftermarket selection of the three; check availability before falling for a strap.
- The integrated exceptions: Ironman and digital Expedition resin straps. No width exists; only the caseback model number matters.
Finding your own number if the table misses it
Timex reference numbers live on the caseback (the TW2... or T... code), and the model number is what Timex's replacement-strap catalogue indexes by. If your reference is not in the table, measure the gap between the lugs where the strap sits: the measuring guide covers the technique, and the lug width chart explains what the number means across brands. For case diameter and lug-to-lug on popular references, the watch database carries dimensions, and the general band size chart sets Timex's widths in the context of every other brand.
