A watch collection is an investment in objects that improve with care. The movement that stays wound maintains its accuracy and lubricant distribution. The case that's stored properly avoids scratches and dust. The strap that's chosen correctly extends the life of both itself and the watch it's worn on.
Most collectors think carefully about winders and storage. Fewer think carefully about straps — even though a strap worn in the wrong conditions can damage a significant watch, and the right strap worn in the right context can transform how a watch reads on the wrist.
This guide covers all three: the winder decisions that matter, the storage choices worth making, and the strap selection that completes the collection.
Part One — Watch Winders
A watch winder serves one primary purpose: keeping an automatic movement wound when the watch isn't being worn. For a collector with more watches than wrists — the common condition — a winder eliminates the need to manually wind and reset each piece before wearing it.
When a winder is necessary:
Watches with perpetual calendar complications — those that track the date, day, month, and sometimes moon phase — are the most important candidates for continuous winding. Resetting a perpetual calendar after it has stopped is a time-consuming process that varies by manufacturer. A Patek Philippe perpetual calendar, an IWC Portugieser Perpetual Calendar, or a Jaeger-LeCoultre Master Perpetual requires the kind of careful resetting that most collectors prefer to avoid.
Simple date complications — the date window at 3 o'clock on a Rolex Submariner, for example — are easily reset and don't justify a winder on practical grounds alone. For these, the winder decision is about convenience rather than complication management.
The rotation settings that matter:
Not all automatic movements require the same winding programme. The turns per day (TPD) and direction of rotation vary by manufacturer:
- Rolex: 650-800 TPD, bidirectional
- Omega: 650-800 TPD, bidirectional
- IWC: 650-900 TPD, bidirectional
- Patek Philippe: 650-800 TPD, clockwise
- Tudor: 650-800 TPD, bidirectional
- Seiko: 650-800 TPD, bidirectional
Over-winding is rarely a problem with quality automatic movements — the slipping clutch mechanism prevents excessive tension. Under-winding, however, can result in a watch that runs but not accurately. Setting the winder to the manufacturer's recommended TPD and direction ensures optimal timekeeping.
Carbon fibre and premium materials:
The winder housing contributes to the watch's storage environment. Carbon fibre — the material used in Aevitas's premium winder range — provides electromagnetic shielding that protects movement components from magnetic field exposure. Given that modern environments are increasingly saturated with magnetic fields from smartphones, tablets, and wireless charging equipment, this protection is more relevant than it once was.
Part Two — Watch Storage and Cases
The case environment:
The optimal storage environment for a watch collection is consistent temperature, low humidity, and minimal UV exposure. Fluctuating temperatures cause expansion and contraction in case materials; high humidity accelerates oxidation on case metals and degradation of leather straps; UV exposure fades dials and degrades rubber compounds over time.
A quality watch case or box provides:
- Cushioned individual compartments — prevents cases from contacting each other
- Fabric lining — typically suede or microfibre — that avoids case scratching
- Closure mechanism that minimises dust ingress
- Opacity — UV light is blocked
Separating watches from straps in storage:
One storage decision that significantly extends both watch and strap life: storing straps separately from the watches. A leather strap left buckled on a watch in storage gradually creases at the buckle hole. A rubber strap stored in contact with a leather strap can transfer compounds. A nylon strap left damp after water activity and stored buckled on a watch introduces moisture to the case.
Storing straps flat in a separate strap roll or drawer — unbuckled, away from direct contact with case metals — extends their usable life significantly.
Part Three — Choosing the Right Strap for Every Occasion
The strap decision is where most collectors have the most room to improve. A collection of five watches with one strap each has five looks. A collection of five watches with three straps each has fifteen — covering formal, sport, and casual contexts for every reference.
The material decision drives everything else.
Nylon — for everyday wear, travel, and active use
Single-pass nylon — one continuous piece of fabric threading over both spring bars and behind the watch case — is the construction that originated in military specification watches and remains the most practical choice for active daily wear.
The specific advantage of single-pass construction for collectors: if one spring bar fails, the watch stays on the wrist. For a collector wearing a significant piece in an environment where a dropped watch risks damage, this security is worth understanding.
Quality nylon breathes better than rubber, dries faster than leather, and at its best has a woven texture that reads as considered rather than casual. On a Tudor Black Bay, a Hamilton Khaki Field, or a vintage-inspired dress watch, nylon watch straps in olive, stone, or navy suit the heritage character of the reference without demanding formal context.
The washing instruction that extends nylon strap life: hand wash in lukewarm water with mild soap after sustained sweat or salt exposure. Air dry flat. Never machine wash — the agitation damages the weave structure and distorts the strap.
Rubber — for water, sport, and outdoor activity
FKM fluorocarbon rubber is the material that Omega specifies on the Seamaster Planet Ocean Rubber, Tudor on the Pelagos FXD, and Rolex on their rubber references. The chemistry explains why: FKM is chemically inert to seawater, sunscreen, chlorine, and UV radiation — the four substances that degrade every other strap material with sustained exposure.
For collectors who swim, dive, sail, or simply live in warm climates where sweat is a constant, rubber watch straps in FKM are the correct daily choice. The surface can be wiped clean with a damp cloth. The material doesn't absorb salt or biological matter. UV exposure that would crack standard rubber compounds doesn't affect FKM's properties.
The one maintenance requirement: rinse with fresh water after salt exposure. A thirty-second rinse after a swim or sail removes salt crystals that would otherwise accumulate in the strap's texture over time.
Leather — for formal occasions and dress contexts
Full-grain calfskin is the only leather grade that develops a genuine patina with wear — deepening in colour at contact points, acquiring a burnished quality that reflects the history of the watch it's worn on. Top-grain and corrected-grain leather, which account for most aftermarket straps at mainstream price points, look correct when new and deteriorate steadily thereafter.
For a collector choosing leather watch straps for formal occasions — the opera, a board meeting, a wedding — full-grain calfskin in slim non-stitch black or warm brown vintage two-stitch is the construction that reads as deliberately chosen. The absence of visible stitching on a non-stitch strap mirrors the restraint of a well-made dress watch dial. The vintage two-stitch references the original strap constructions of the 1960s and 1970s that appeared on Heuer Carrera and Omega Speedmaster references.
The leather storage instruction that most collectors overlook: store leather straps unbuckled, flat, away from direct sunlight. A leather strap left buckled for weeks creases permanently at the buckle point. A leather strap stored in a drawer away from UV maintains its surface and ages gracefully rather than drying and cracking.
The Complete Care System
The collector who combines a quality winder programme, thoughtful storage, and a considered strap rotation gets the most from every piece in the collection:
- The movement stays wound and accurate
- The case stays scratch-free and dust-free
- The strap suits the occasion and extends its own life through proper maintenance
Each element supports the others. A watch stored correctly and wound appropriately is worth wearing. A watch worth wearing deserves a strap that suits it. The complete system costs less than most collectors assume and extends the life and enjoyment of a collection significantly.
