The Timex W-4 instruction sheet marked W4 910-095015 NA explains how to set the day and date, but “W4 / 910” alone does not identify a specific watch configuration or confirm its battery or band size. Check the complete marking on your watch’s caseback before ordering parts. Timex’s manuals page groups instructions by watch type and model details.
What does “Timex Caliber W4 / 910” identify?
The official Timex W-4 guide available for this family is marked W4 910-095015 NA. Its instruction sheet cautions that “Your model may not have all of the features described in this booklet.” The shortened wording “W4 / 910” is not enough to establish that your watch is the exact configuration covered by that guide.

A separate transcription uses the identifier 910-095007, which is another reason not to infer the exact model or parts from the abbreviated name. Read the full style or model marking on your watch’s caseback and match it to the documentation before relying on instructions or ordering replacements. Timex’s manuals page does not specify a battery or band for the abbreviated “W4 / 910” wording.

For a watch covered by the W-4 guide, set the date first, then follow the guide’s day and date setting directions. The guide warns against leaving the crown in its middle position: “Wearing or storing the watch with the crown in the ‘middle’ position will cause damage to the movement.”

What battery does a Timex W4 910 take?
The available W-4 instructions and Timex manuals listing do not establish a battery specification for the abbreviated title. Do not choose a coin-cell battery based only on “W4 / 910.” Check the complete caseback marking and ask Timex or a watch repairer to confirm the correct battery for that exact watch.
