A Time to the Hundredth
Ask a swimmer what they did last season and you will get a number. Not a placing, not a story — a time, to the hundredth. Swimming is the sport most completely organised around a single figure, and swimmers can usually recite theirs years after they stopped racing.
That makes it close to a perfect engraving. It is precise, it is earned, and it means nothing at all to anyone who does not know the sport.
Fitting a time on a plate
A time like 2:04.31 is seven characters, which sits inside the four to ten character tier with room to spare. A shorter time, or a distance like 200 FR, fits comfortably too.
If you want something shorter, one to three characters takes initials or an event number. If you are buying for someone else, their personal best is the detail worth checking rather than guessing — a wrong time is a strange thing to wear.
The one sport where waterproof is not marketing
Every piece here is 316L stainless steel, waterproof, tarnish resistant and hypoallergenic, in polished steel or 18K gold PVD. For most sports that is about sweat and rain. For swimming it is about the actual water, and about chlorine, which is harder on plated jewellery than anything a footballer will put it through.
A practical note: most competitive bodies have rules about jewellery in racing, so this is a piece for training, for the deck and for the rest of life rather than for a race.
Length
Chains come at 18 and 20 inches. Eighteen sits closer to the collarbone, which tends to suit swimmers wearing it over a t-shirt on deck rather than under one.
Engrave the time. It is the number the work went into.
