1. A mobile indicating time information or information derived from the time,
wherein the mobile comprises at least one first obstacle element intended to receive a driving contact action driving the mobile and/or intended to transmit a driving contact action from the mobile,
wherein the first obstacle element is made of titanium or of titanium alloy,
wherein the mobile has substantially annular shape,
wherein the mobile is a calendar mobile, and
wherein the mobile comprises a ring, on which openings are provided at an outer periphery of the ring so as to enable fine adjustment of the inertia of the mobile for a given geometry of the mobile in order to enable the mobile to be driven whilst limiting the energy the driving mobile is required to supply.

3. The mobile as claimed in claim 2 , wherein the first set of teeth has at least 7 teeth.
4. The mobile as claimed in claim 2 , wherein the first set of teeth is designed to cooperate with a first driving finger every hour or every 24 hours.
5. The mobile as claimed in claim 1 , wherein the mobile comprises a second obstacle element and wherein the second obstacle element comprises or is a second set of teeth.
6. The mobile as claimed in claim 5 , wherein the second set of teeth is fixed relative to the rest of the mobile.
7. The mobile as claimed in claim 5 , wherein the second set of teeth comprises one tooth.
8. The mobile as claimed in claim 5 , wherein the second set of teeth is designed to cooperate with a second driving finger at the end of at least some months with fewer than 31 days.
9. The mobile as claimed in claim 5 , wherein the second set of teeth is movable relative to the rest of the mobile.
10. The mobile as claimed in claim 1 , wherein the mobile comprises a third obstacle element and the third obstacle element comprises or is a third set of teeth.
11. The mobile as claimed in claim 1 , wherein the mobile comprises a plurality of obstacle elements disposed on a plurality of levels or in a plurality of parallel planes relative to a rotation axis of the mobile.
12. The mobile as claimed in claim 1 , wherein the mobile is made in one piece.
13. The mobile as claimed in claim 12 , wherein the mobile comprises a support bearing time information or information derived from the time, in particular numeric and/or alphabetic information, the support being integral with a ring.
