Seriously, though, because this particular key chain is also a pocket watch you might consider using one of the suggestions regarding engravings on clocks, watches and sundials :
AGE QUOD AGIS – Do what you are doing
ALIIS INSERVIENDO CONSUMOR – By serving others, I am worn away Note that although originally a sundial inscription, this phrase actually makes a lot more sense for a clock mechanism, it also indicates a particular philosophy of life.
ARS LONGA, VITA BREVIS – Art lasts, life is short
ASPICE ET ABI – Look (at me) and pass on
DEO FAVENTE – With God’s favor
DEUS ADEST LABORANTIBUS – God favors the diligent
DIES DIEM TRUDIT – Each day forces out another day
DISCE DIES NUMERARE TUOS – Learn to value your days
DUM SPECTAS FUGIO – I flee even as you observe me
EX HOC MOMENTO PENDET AETERNITAS – Eternity is hinged upon this moment
FESTINA LENTE – Make haste slowly There is actually a company called Festina that makes clocks and watches. In my opinion, only the complete quote makes sense. Who would want a clock that is too fast? The phrase indicates a perfect balance that must be achieved in a clock and in life.
HINC VIVERE DISCE – Learn to live by this example
HORA PARS VITAE – Every hour is a part of life
ITA VITA – Thus (passes) life
LABOR IPSE VOLUPTAS – Labor contains pleasure
NE QUID PEREAT – Let nothing be lost
NON NOBIS NATI SUMUS – We are not born for ourselves
NON REDIBO – I shall not return
NOSCE TEIPSUM – Know thyself
OMNIA FALCE METIT TEMPUS – Time reaps everything with its sickle
OMNIA FERT AETAS – Time brings all things
POST TENEBRAS SPERO LUCEM – I hope for light after darkness
QUID CELERIUS TEMPORE? – What is swifter than time?
SAPIENTIS EST NUMERARE – It is the wise who count
SIC TRANSIT GLORIA MUNDI – Thus passes the glory of this world
ULTIMA DECIDET – The last one decides
UMBRA DEI – The shadow of God
VERITAS TEMPORIS FILIA – Truth is the daughter of time
VIGILATE & ORATE, TEMPUS FUGIT – Be vigilant and pray, for the time hastes away
