Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an agent to recognise a watch, assess its timekeeping and physical condition, and determine appropriate use, adjustment and care.
A watch is a portable timekeeping instrument designed to be worn on the person or carried in a pocket, using a regulated mechanism or electronic timebase to indicate time.
It can be Read time and supported calendar or timing indications while checking their reference and interpretation.; Set time, date, time zone and supported functions using the watch's documented control sequence.; Wind, charge or arrange cell replacement according to the installed energy system.; Fit, fasten or replace a compatible strap, bracelet or carrying attachment.; Assess suitability for a proposed exposure using protection claims, condition and service evidence.; Diagnose basic timekeeping or connection problems and route unsupported repairs to an appropriate service provider..
Distinguishing features
It is designed to function as a personal timepiece worn on the body or carried with the person, rather than installed as a stationary clock.
Its intended functions include indicating time of day; elapsed-time measurement alone is insufficient to identify it as a watch.
Its design and controls support use as a watch; merely displaying a clock on a phone or another device does not establish membership.
Wrist attachment is not required: a pocket watch remains within scope.
Brand, operating system and product generation identify narrower watch families or products rather than defining the registered kind.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 19 findings · 29 questions.
Timekeeping and reference How the watch maintains time and how its indications relate to an external reference.
A watch can display the wrong time because of drift, incorrect setting or failed synchronisation; these require different actions.
Movement and regulation
The installed timekeeping mechanism and evidence about its performance.
Identify the timekeeping mechanism
Record the movement or electronic timekeeping implementation separately from the appearance of its display.
- What mechanism maintains time, and what identification or documentation establishes it? provenance
- What rate deviation is observed over a stated interval, with position, temperature and synchronisation events recorded where relevant? measurement
Reference and correction
The reference, time-zone interpretation and correction behaviour behind displayed time.
Establish the time reference
Distinguish current offset, zone selection and external correction from the watch's underlying rate.
- Which reference and time zone should the watch indicate, and what is its measured offset from that reference? measurement
- How is time corrected, and what happens when the correction source is unavailable or the time zone changes? action
Indications and controls How watch indications are interpreted and how supported functions are operated.
Hands, subdials, windows and screens can represent different quantities, while setting controls may have movement-specific restrictions.
Readable indications
The meanings and usable conditions of the watch's displays.
Interpret the watch display
Identify each indication without assuming that every hand or numeric field represents ordinary time of day.
- Which hands, windows, subdials or screen fields show time of day, date, elapsed time or another quantity? definition
- Under what lighting, viewing and power conditions can the required indication actually be read? measurement
Setting and complications
Controls and operating sequences for time setting and optional watch functions.
Operate supported functions
Record crown positions, pushers, bezels or screen interactions together with documented restrictions.
- What control sequence sets time and operates each installed calendar, alarm, chronograph or additional-zone function? action
- Does the documented mechanism impose restricted calendar-setting periods, crown-locking steps or conditions on pusher use? provenance
Wearing and exposure How the watch stays attached and what evidence supports its use under physical exposure.
A functioning movement is insufficient if the watch cannot be secured or its case protection is unsuitable for the intended activity.
Fit and retention
Wearable or carrying geometry and the condition of retention components.
Secure personal carrying
Assess the strap, bracelet, clasp, spring bars, chain or other attachment appropriate to this watch form.
- What dimensions and connector types determine fit and attachment compatibility for this watch? measurement
- What inspection or adjustment is needed to establish that its clasp, connectors or carrying chain retain it securely? action
Case and environmental protection
Case integrity and documented limits for water, impact, magnetic fields and temperature.
Evaluate exposure suitability
Keep design claims, markings and current condition distinct when deciding whether an exposure is appropriate.
- Which manufacturer instructions, test records or standards with identified issuing bodies support the watch's claimed exposure limits? provenance
- Do crystal damage, seal history, crown position or observed moisture change whether the proposed activity is permissible? action
Energy and service How the watch receives operating energy and how faults or deterioration are addressed.
Spring winding, cell replacement and rechargeable operation require different interventions, and opening the case can affect protection.
Energy replenishment
The installed energy system, available reserve and compatible replenishment method.
Maintain operating reserve
Determine how to restore energy without assuming that all watches can be wound, charged or opened in the same way.
- What supplies energy, and what winding procedure, cell specification or charging equipment is documented as compatible? provenance
- What remaining runtime or full-reserve runtime is observed under the stated pattern of use? measurement
Faults and maintenance
Symptoms, service evidence and boundaries between ordinary care and specialist intervention.
Triage watch condition
Record symptoms without prematurely assigning a cause, then identify supported checks and service needs.
- Does the watch stop, drift, show misaligned indications, lose reserve or exhibit condensation, and when do these symptoms occur? measurement
- Which documented checks or cleaning actions are appropriate, and which repairs require specialist work or protection testing afterward? action
Connected watch capabilities Conditional modelling of connectivity, software and sensing where the watch includes them.
Connected watches introduce dependencies and data actions, but these must not become requirements for mechanical or unconnected watches.
Standalone and paired operation
Which watch functions depend on another device, account, network or software state.
Map watch dependencies
Identify optional dependencies while reserving product-specific details for narrower watch models.
- Which timekeeping, alarm, notification and other installed functions remain available without a paired phone, account or network? boundary
- Which pairing, update and recovery procedures apply to the identified product and installed software version? action
Sensing and personal data
Optional sensor outputs and the handling of information stored or transmitted by the watch.
Bound sensor and data actions
Record available outputs and operational constraints without treating sensor readings as established health conclusions.
- Which sensors and outputs are documented, and what fit, calibration or operating conditions limit their interpretation? provenance
- What authorised steps export or erase personal data and remove pairing or account associations before transfer or service? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- Which documented setting restrictions, servicing requirements and exposure limits vary by movement rather than by broad watch category?
