Tank Style Watches for Women Under $100

The Lucky Fours Calista: the rectangular case, Roman numerals and a gold link bracelet

Some watch designs are about function: telling the time underwater, timing a race, reading a second time zone. The rectangular dress watch with long side rails is about none of that. It was drawn in the years around the First World War as a pure piece of design, and it has stayed in production at the top of the market for about a century, worn by people who want to look well dressed without trying to look rich. In gold, the best known versions sit in the gold dress watch bracket, from about $17,500.

The shape itself is simple enough to be done well at a very low price, which is why this guide can be honest about its title. There is one good tank style watch for women under $100, and a few more just above it.

What makes a tank style watch

Four details define the shape, and a good affordable version gets all four right.

Proportion matters more here than on any round watch. A tank should be noticeably taller than it is wide, and small. Once the case goes much over 25mm wide on a woman's wrist, the elegance starts to drain away.

The best tank style watch under $100

The Lucky Fours Calista is the only watch we would recommend in this style under $100, and it is a good one. It has a rectangular gold tone case with defined side rails, a white dial with Roman numerals arranged around the rectangle, and a gold link bracelet. On the wrist it reads as a classic dress watch in jewelry form, the bracelet making it easier to wear every day than a leather strap would. It is $79.99, and there are 4 colorways, including versions with stones on the case and a silver tone option.

Which colorway? The plain Gold is the most classic. The versions with stones on the case are more of an evening watch; if you choose one, keep other jewelry simple, as we explain in iced watches that do not look cheap. The silver tone version suits anyone who mostly wears silver jewelry.

Just above $100

To be clear about the title: the following watches cost more than $100. We include them because they are the natural next step, and because a guide that stopped at one watch would not be much help.

The Lucky Fours Phila is a smaller and finer rectangle than the Calista, a small rectangular dial on a thin gold bracelet with a distinctly vintage feel. It is the version we would choose for a very slim wrist or for someone who wants the watch to read more as jewelry. It is $139.99.

The Lucky Fours Milo is strictly a square rather than a tank, a small square gold dial on a gold bracelet, but it is often considered alongside. It is $149.99. Our guide to square and rectangular watches sorts all the shaped families.

From an established brand, the Timex 1976 Lexington Reissue 21mm at $159 is the most traditional option here: a slim 21mm gold tone rectangle with a vertically brushed silver tone dial, elongated Roman numerals and a fine handset on a leather strap. Timex lists it as a men's watch, but at that size it suits most women's wrists, and Timex itself describes it as at home on any wrist. The Timex Hailey 24mm, listed at $104.99, is a small rectangle with crystals on the case and an emerald dial, which is a more modern and decorative take on the shape.

How to wear a tank style watch

A tank sits best on the inside of a loose cuff or just above the wrist bone, close enough to stay straight. On a bracelet, remove links until the case cannot rotate; a rectangle that slides sideways looks wrong in a way a round watch does not. Pair it with a simple gold bangle or a single fine chain, or wear it alone. It works with a blazer, a silk blouse or a white T shirt, which is the secret of its century in production.

Frequently Asked Questions

What is a tank style watch?

A rectangular dress watch whose long sides extend beyond the dial into the strap or bracelet attachments, usually with Roman numerals and a fine minute track. The name comes from a design said to be inspired by the outline of a First World War tank seen from above.

What size tank watch should a woman wear?

Most women's tank style watches are between about 20 and 25mm wide. The length, top to bottom, should not overhang the wrist. Our guide to small watches explains how to measure.

Is a tank watch better on a bracelet or a strap?

Traditionally on leather, which makes it a pure dress watch. On a gold link bracelet it becomes more like jewelry and easier to wear every day. Both are correct.

Can a tank style watch be worn every day?

Yes. It is a dress watch by origin, but its small size and simple dial make it one of the most versatile women's watches, at home with jeans as well as tailoring.
