The 5 Best Watches under $100
Under $100, a watch should earn its place on your wrist through readability, fit and the job you actually need it to do. I would not compare a tiny digital Casio with a large dive-style Casio as if one were simply a more expensive version of the other. One disappears under a sleeve; the other is meant to be seen and worn around water.
Casio F‑91W is my easiest low-cost daily pick: digital, light and uncomplicated. MDV‑106 is the larger steel-case choice for swimming and water use; Timex Easy Reader is for a clear analog dial. Expedition Rugged Core adds a field-watch feel, while Weekender keeps the casual changeable strap. I would check case diameter before buying: the F‑91W and MDV‑106 feel like watches from entirely different size classes.

01 — Casio
Best inexpensive daily digitalCasio F‑91W
F‑91W is the tiny digital Casio I would wear when I want the time, date, alarm and stopwatch without carrying a heavy watch. Casio lists a 21-gram resin body and an approximately seven-year battery under its stated conditions. Its small light and basic water-resistant designation are not a substitute for the MDV‑106's larger display or 200-meter specification.
It leads because it does its narrow, everyday job cheaply and with little fuss. I would choose Easy Reader if analog legibility matters or MDV‑106 for a substantial water-ready case. The F‑91W is digital, whatever an older generic description may have said.

You want a large analog dial or dive-style case.
What I like
+Very light resin body and basic functions.
What to weigh
−Small light and modest water designation.

Best dive-style valueCasio MDV‑106
MDV‑106 is a different proposition: Casio specifies a 44.2mm-wide stainless-steel case, rotating bezel, screw-lock crown and 200-meter water resistance. That makes it feel substantial and gives it a clear water-use role, but the size and weight may overwhelm a small wrist. Follow Casio's crown and maintenance guidance before any water activity.
Second place rewards unusually clear watch construction for the price, not a claim that everyone needs a dive watch. I would buy F‑91W for light daily use and MDV‑106 when its analog face and water specification genuinely matter. Confirm the exact listed variant and strap.

A compact or dressy wrist fit matters most.
What I like
+Steel case and 200-meter specification.
What to weigh
−Large 44mm-class body and added weight.
03 — Timex
Best large readable analogTimex Easy Reader 38mm
Easy Reader is for someone who wants to glance at large numerals rather than decode a small digital face or a busy field dial. Its 38mm case sits between the small F‑91W and larger MDV‑106. Check the exact band, date window and backlight on this Amazon variant: Timex uses the Easy Reader name across many similar configurations.
Third place is a readability decision. I would buy it for a parent who prefers an ordinary analog dial, choosing Weekender when strap changes and casual styling matter more. It does not offer the Casio diver's water specification.
Specifications: Timex Easy Reader 38mm collection ↗
View on Amazon ↗Buyers who value a clear analog face.
You need a strong water-use rating.
What I like
+Simple large numerals.
What to weigh
−Variant features and band need checking.
04 — Timex
Best rugged everyday stylingTimex Expedition Rugged Core
Expedition Rugged Core gives a buyer who likes a field-watch look a larger approximately 43mm analog body. I would check the printed hour markers and strap against your own wrist size rather than assume 'rugged' means an unlimited water or shock rating. It has more visual presence than Easy Reader, but less of that model's plain at-a-glance dial.
Fourth place is for style and fit, not a blanket toughness claim. I would buy it when I want a casual outdoor-looking watch at modest cost. For genuine planned water use, Casio's documented MDV‑106 is the clearer comparison.

A small case or simplest dial is preferred.
What I like
+Clear casual outdoors aesthetic.
What to weigh
−Size and resistance need model checks.
05 — Timex
Best casual strap-changing watchTimex Weekender 38mm
Weekender 38mm is for someone who treats the strap as part of the outfit. Its slip-through nylon band can be exchanged more casually than the fixed look of a resin sports watch, and Timex's INDIGLO illumination is useful after dark. Check the exact strap length and case finish in this listing; the fabric band also needs drying after a wet day.
It closes the general list because its strength is personal style rather than the Casios' specific utility. I would buy it as a casual second watch, and Easy Reader if large numerals are the reason to shop. The strap is the choice, not a hidden performance upgrade.

What I like
+Easy-to-change fabric band and INDIGLO.
