Measure at home in 2 minutes
You need a strip of paper (or a string or shoelace), a pen and a ruler.
- Take a string or a shoelace and mark on it the length you are considering, for example 56 cm (22").
- Hold the two marks together at the back of your neck, wearing the kind of top you usually wear.
- Look in a mirror: the lowest point of the string is where the chain will sit.
- Too high or too low? Try 5 cm (2") more or less: that is one size up or down.
Already own a chain you like? Lay it flat, clasp closed, and measure it end to end. A broad neck or chest makes every length sit a little higher.
No ruler? A bank card is 8.6 cm (3.4") long: count how many fit along your strip.

A clean line at the collar, with two inches of give.
Atlas took the whole sky on his back and kept walking. You keep walking too, and this chain keeps pace. The box chain sits close to the neck in one smooth line, its square links breaking the light into short flashes rather than a wide shine. A 2-inch extender at the clasp lets you set the drop. Silver, gold-tone or rose gold-tone, in a 2mm or 3mm width.
- Stainless steel that stays on in water
- 2 in (5cm) extender at the clasp
- Three tones, two widths
Details & specs
MaterialStainless steel
Chain styleBox chain
Width2mm or 3mm
Length17" (43cm) or 18.5" (47cm), extender included
FinishNatural steel, or gold-tone or rose gold-tone plated
ClosureLobster clasp with 2" extender
Stainless steel box chain, made from uniform square links that lock together into a flat, even line. The square shape keeps its form instead of twisting like a rope chain. Stainless steel does not rust, so hands, sweat, showers and salt water are part of an ordinary day for it, and you can leave it on.
Silver is the natural steel; gold-tone and rose gold-tone are electroplated finishes. Each chain closes with a lobster clasp and carries a 2" (5cm) extender, so you can shorten or lengthen the drop by a couple of inches without changing the look. The 2mm is slim and minimal, the 3mm a touch more present.
How to wear it
With a white tee it reads as a clean strip of metal at the neckline; under an open collar it shows in glimpses as you move. Match the finish to your watch and rings: silver with steel, gold-tone with gold hardware. It works for the office, dinner and weekends, and the 2mm takes a small pendant without looking crowded.
Choosing your size
The 2mm width comes at 17" (43cm) in total including the extender, which sits high on the neck, near the collarbone. The 3mm width comes at 18.5" (47cm) in total, a little lower and closer to the top of the chest. For a closer, more minimal fit, take the 2mm; for a broader neck or a looser drop, go with the 3mm.
Why this piece
A shape that stays sharp
Square links give the box chain a flat, geometric line that keeps its form instead of twisting.
Made for the water too
Stainless steel does not rust and does not turn your skin green, in the shower, at the gym or at the beach.
For the man who carries everything
A simple gift for a partner or a brother. Both versions have a 2" extender, so the fit adjusts; 3mm at 18.5" is the safer pick, and you have 30 days to return it.

Questions
Can the box chain with extender in rose gold-tone go in the sea?
Yes. The stainless steel does not rust, so hands, sweat, showers and salt water are an ordinary day for it. Rinse the gold-tone or rose gold-tone in fresh water after a swim to keep the plated color even.
Will the 2mm box chain hold a small pendant?
Yes. The 2mm takes a small pendant without looking crowded, and the 2" (5cm) extender lets you set it a little higher or lower on the neck.
How do I care for the plated colors?
Wipe the chain with a soft dry cloth after wear and store it away from perfume, lotion and cleaning products. Avoid abrasive cleaners, as the gold-tone and rose gold-tone colors are plated.
Is the length tied to the width?
Yes. The 2mm comes at 17 in (43cm) and the 3mm at 18.5 in (47cm), both measured with the 2 in (5cm) extender included.
How does a 2mm chain look on a man?
Slim and minimal: a clean strip of metal at the neckline with a tee, and glimpses of it under an open collar.
Is the rose gold-tone plated?
Yes. Gold-tone and rose gold-tone are electroplated finishes; silver is the natural steel.
Does the extender show from the front?
No. It hangs at the clasp, at the back of the neck, so from the front you only see the chain.
Can I return it if it is too short?
Yes. Return it unworn, in its original Atlas packaging, within 30 days of receiving it; return shipping is at your cost.
